This is absolutley one of the most informative and straight-forward videos that I have seen on youtube. Thank you for making and posting it. I strongly agree with the many other viewers encouraging/requesting that you please continue to make and post future videos. A hearty "Well Done" from across-the-pond.
looking at the insides of this pistol we could all see the gas valve (it had a red strip across it), and it's the lowest power valve as only the low power valve has the red stripe, if you change this valve for the 8-inch barreled pistol valve, that has no red strip across it, that would bump up the power far more than pushing the hammer spring to its limit and in doing so you make the trigger pull much harder, however changing the gas valve come's at a price, but it's money well spent
Its a m4 nut and screw..but!! It does nothing to my pellet version ive screwed the screw in as far as it goes in and over my chronograph theres is absolutely no power increase 👍
Awesome vid mate, I've just bought the umarex legends s25 version of this revolver.... at some point in the future I might up the power so this vid is excellent
Did you Chrono the Dan Wesson? I suspect that even with this modification it would only put the gun at around 3ft lb - Im in Durham with a Chrono if you would be interested in adding numbers to this video. Regards
Should be effective and it is definitely interesting. However there are some cons to this method since all tuning is actualy a compromise isn't it. increased trigger pull weight which also increases the rate of wear upon the trigger bearing surfaces and finally increased co2 release /less shots per bulb. Still I might give it a go.
The nut and bolt are not going to give you more power to the air valve only to the trigger spring. By changing the rubber bb insert to the bottom of the cartridge you will have more power.
david, hello. enjoyed your tune up video re dan wesson. i have a ruger super hawk 6mm co2 [8"] can i use this mod on my ruger, how far can you tighten the screw, is it a case of trial and error? what about the best type of bb's best to use? any more videos on this tune up subject coming up? thanks
two questions, this can not cause long-term damage to the weapon? and lose more gas than normal? that is, a bottle lasts 60 shots for example, will this modification decrease that amount? a greeting.
OK...I just received my 2.5in Dan Wesson Pellet gun. With the barrel pointed down, I noticed there is an air gap between the cartridge and the little black seal on the rear of the frame...about the width of a pocket knife blade. If I push the cylinder back towards the hammer, the gap goes away. Do I have a defective airgun?
hi thanks for this info . i have done the small nut on my dan wesson works great . is there anything i should do to the shells . thanks i know im 7 years late lol
This is the only Co2 I know of that you can do this with thanks for asking,and sorry for not getting back to you all,but I'm so busy at the moment and with my five kids I just don't get much time on here,thanks.
Haha OK sounds like ur Chrono is already on FPS and not MPS 315fps sound correct I put in a 0.41356 gram blitzo bb in mine & it shot so fast it went back in time
Does anybody know where to get parts for these things at all. Mine dumps the co2 out nearly instantly. I cant find a replacement valve, or gasket kit anywhere. Theres no numbers stamped on the valve, no nothing. Any help would be appreciated.
Hey there Mr Robinson can you please help me. I'm trying to increase the FPS on my Dan Wesson 8 inch revolver BB and I can't modify it due to its really, really tight screw. The last two that the handle covers are the ones that I'm having trouble with, which is kind of strange due to its size; I can bench press nearly 300 pounds ( so you can understand my frustrations), can you please tell me how I can unscrew them without damaging the gun or the screw?
Hi, I have the 1 joule (downgraded) version of the 6" Wesson. Do you know the method the manufacturers "downgraded" the gun? Is it with a weaker hammer spring, a stronger valve spring or would it be something else which limits the power (such as a smaller valve)??
+Onyx BlackScale Hi I also have a DW 6mm 6" marked with a 1 Joule label. How do I identify the Power down shells from the normal shells. I purchased extra Shells (with no power down labelling) but do not see the difference with the shells provided with the gun. Any idea how to distinguish between these shells
full power are a browny orange and low power are a yellow colour, im not aware of any internal mods, mine with full power hits 440 low power 320 the low power just have a smaller gas flow hole
+Onyx BlackScale Hi thanks for the identification of the LP Shells. My gun came with the brown coloured shells I'm still bewildered as to why its labelled as 1 Joule. Would 1Joule of power with 6mm steel BB's achieve 440 FPS
Hi,I'm not sure why it is lose but know that some are and I would take it back to the shop,but if that's not possible like mine as I striped them so mine was lose so I used plumbers tape on the back of the barrel but its tricky to do and used a very small amount of glue to keep it tight then put some in the pin holes then put pins in its been fine and had no problems,as there's not much you can do to make it fit better or be solid,that's the only bad thing about this gun.
So I'm going to go out on a hunch here that the Crossman SNR. 357 and the Dan Wesson 715 are the same air pistol. Everything is the same . The Dan Wesson 715 2 Gen is different though.
Many thanks for the video dood. Very informative, Is it the same setup in the ASG Dan Wesson 715 6" Revolver? I would like to be able to tweak the power down slightly without running low power shells as these reduce the fps too much. My only other option is to drill out the centres of the low power shells to find a happy medium between the low and standard power. Thoughts?
Excellent video, whens the next installment??.. May I please request your next video is also a revolver.... :P I am getting the 2.5mm next week... any further info on these guns is greatly appreciated
Great idea. I suggest to polish te "front surface" of the screw an apply some grease on it, so the aluminium "cup" wount wear too fast. By the way.. I just bought one and thinking of regrease it from factory greases. There is a problem because i dont know which oils/greases put on different surfaces. If You have some free time, please make the video about it. It will be sweet;-)
AWESOME VIDEO BUD !!!!! 1.) HAVE YOU CONSIDERED BORING OUT THE INTERNALS OF CO2 VALVE TO HOLD MORE CO2 ? ,2.) ALSO MAYBE BORE OUT THE CO2 EXHAUST TUBE THAT FEEDS CO2 TO THE BARREL ! 3.) AND ALSO , HAVE YOU EVER MODDED THE CROSMAN 357 REVOLVER ,IT HAS SO MUCH POTENTIAL !!!
Great video and explanations! is there a possibility to put a gas canister that will be filled with air to turn it in to a pcp air gun? i'm thinking to replace the co2 cartridge and give it some more power. i have the ruger superhawk airsoft and i have replaced the inner barrel with a 60cm one(not for airsoft animore as it has too much speed) i use it for backyard target shooting
thanks bud, you sounds geordie? im from consett, and i see you have lots of extra cartridges, where would you advise me getting them? havnt actually bought the gun yet but ill need some extra cartridges.
I don't live that far from you mate I'min Durham,I bought my extra cartridges from ebay but not sure if they sell them now but if you just look on the Internet you will find loads that sell them,thanks for asking.
I whant do this to mine Ruger of Umarex its also a WG but its a 8 shooter instead of 6 and easy to load to, But i whant less power how i can do that the best weaker spring , its 360 Max in my country fore side-arms
I know this is an old post but I've found this very useful. I use mostly 6mm airsoft replicas and I'll try using this method to actually lower the fps in my Co2 revolvers. Do you know if other wingun revolvers have similar internals?
you gotta find the valve somewhere. I only know magazine operated airguns have this valve to tighten that i will use scissors or thin pliers since they key you have to buy.
This is absolutley one of the most informative and straight-forward videos that I have seen on youtube. Thank you for making and posting it. I strongly agree with the many other viewers encouraging/requesting that you please continue to make and post future videos. A hearty "Well Done" from across-the-pond.
Well said mate. Spot on.
This modification is great, but if you take off the co2 valve and open it and make the washer inside much thinner you get alot more power.
Does this work?
And do you know of any other possible modifications?
I always enjoy watching a pro at work. Well done sir!
Pretty informative and professional way better than just sticking cardboard in anyway
Great to see someone who actually knows what he's doing. Sub'd.
There no fps test before and after
So how do you know it works
By increasing the spring force, the trigger button also needs more force, and it will break before time!
thanks David --did this mod to both my dan wessons and worked perfectly. Great mod. Subscribed for more tips from the Doctor.
Very creative way to power it up a little place and 2 screws madness thanks for an idea
Cual eran las potencias antes y después de esta modificación ?
The trigger also hardens, making it harder to fire! the firing mechanism is failed
looking at the insides of this pistol we could all see the gas valve (it had a red strip across it), and it's the lowest power valve as only the low power valve has the red stripe, if you change this valve for the 8-inch barreled pistol valve, that has no red strip across it, that would bump up the power far more than pushing the hammer spring to its limit and in doing so you make the trigger pull much harder, however changing the gas valve come's at a price, but it's money well spent
Its a m4 nut and screw..but!! It does nothing to my pellet version ive screwed the screw in as far as it goes in and over my chronograph theres is absolutely no power increase 👍
Seguro que es una M4. Podeis poner las medidas del tornillo y la tuerca?
Excellent video David, thanks very much. Just followed it word for word and mod done!!
Awesome vid mate, I've just bought the umarex legends s25 version of this revolver.... at some point in the future I might up the power so this vid is excellent
its the same here in canada, our guns have "low flow" valves and no power adjustment
So, that is basically the hammer spring we are screwing tight with the help of new nut and bolt. Right??
Just one question, and firstly thank you for this video! Will this work in increasing output power for the .177 pellet version as well?
It only makes it more consistent with the power
Did you Chrono the Dan Wesson? I suspect that even with this modification it would only put the gun at around 3ft lb - Im in Durham with a Chrono if you would be interested in adding numbers to this video. Regards
How exacly this mod works? And have you messured difference befor and after mod?
A chrono comparative test before/after would be necessary.
thx man the best tutorial i've found so far
PS: I think it's a M4 screw
Was it def a m4 screw?
This is a brilliant video,it's the best way by far to power up this gun,please make more videos!
I just did this mod. it was the easiest mod I've done yet. I added blue loktite to the exposed screws.
Should be effective and it is definitely interesting. However there are some cons to this method since all tuning is actualy a compromise isn't it. increased trigger pull weight which also increases the rate of wear upon the trigger bearing surfaces and finally increased co2 release /less shots per bulb. Still I might give it a go.
Hello there, I live in the US and was hoping you could share your insight on cartage modification as their is no speed limit where I am.
brilliant,keep up the good work.looking forward to seeing more videos.thank you.
The nut and bolt are not going to give you more power to the air valve only to the trigger spring.
By changing the rubber bb insert to the bottom of the cartridge you will have more power.
the cartridges made for holding .177 pellets has rubber insert at bottom, will bb also fire from there ?
you must swap valves. take the 6" pistol's valve and put it in the 2.5" pistol, then youll get power increase
Use the shortest bolt you can or the head of the bolt will stop the grip fitting properly making it loose and rocky.
Hey, will this work on the asg 715 Dan Wesson 2.5 inch?
It doesn't give you more power you have to change the valve for more power
Bueno , y como se cambia la válvula ?!?
CORRECT !!! must get valve from 6"-8" barrelled version, put in 2.5" barrelled version then you have more power !
where is the other power up mod on the dan wesson?
Thanks for help i’ve been having a reoccurring issue where the hammer will not strike the gun or the fake firing pin to go off
👍 ... Crosman SNR357 .... I use Hornady and GAMO ... Welcome to my family Dan Wesson is part compatible with the SNR357
It would be best , to.use a crono , to keep a eye on how much power the adjustment is improving too. Nice video
Is there a way to powerup a crosman vigilante? And would you use this powered up pellet for self defence?
How can I get a hold of you for a few questions... I have the pellet and bb version.. cheers
Dr. Gunsmith how am I only finding you now? You are exactly what I'm going to need when shit hits the FAN!
How much more velocity can this modification be expected to yield? Thanks!
Wesson 8 hi power is 540fps but this is the low power version around 425fps but with the mod maybe make it around 450fps
david, hello.
enjoyed your tune up video re dan wesson. i have a ruger super hawk 6mm co2 [8"]
can i use this mod on my ruger, how far can you tighten the screw, is it a case of trial and error? what about the best type of bb's best to use? any more videos on this tune up subject coming up? thanks
awesome job, incredibly simple now that we see it here, thankyou
two questions, this can not cause long-term damage to the weapon? and lose more gas than normal? that is, a bottle lasts 60 shots for example, will this modification decrease that amount? a greeting.
OK...I just received my 2.5in Dan Wesson Pellet gun. With the barrel pointed down, I noticed there is an air gap between the cartridge and the little black seal on the rear of the frame...about the width of a pocket knife blade. If I push the cylinder back towards the hammer, the gap goes away. Do I have a defective airgun?
How can I get in touch with David Robinson - Gunsmith?
Is it the same modification for Umarex Legends S25 177 air revolver thst's the one I have?.
Any suggestion for where I can get the hex nut that is used to tighten the co2?
9/32” (screw)bolt and nut fit perfectly in mine
Nicely done, mate! How hard is it to fit the rifled barrel and where can you get it from? I need it for an 8" though.. Cheers!
hi thanks for this info . i have done the small nut on my dan wesson works great . is there anything i should do to the shells . thanks i know im 7 years late lol
This is the only Co2 I know of that you can do this with thanks for asking,and sorry for not getting back to you all,but I'm so busy at the moment and with my five kids I just don't get much time on here,thanks.
Dr Gunsmith thanks.for.the.great.video.when.you.upen.up.the.gun.will.anything.fly.out
What type or screw and washer was used, size?
Just got the Dan Wesson 715, is this mod the same with mine??
What is the screw and bolt mm he uses when he tunes the power up? Please answer asap.
Haven't done any modifications yet mine shoots 315 meters per second with a .40 gram airsoft bb totaling to 20 joules of power
Haha OK sounds like ur Chrono is already on FPS and not MPS
315fps sound correct
I put in a 0.41356 gram blitzo bb in mine & it shot so fast it went back in time
@@MrM4GooHow do you explain the 20 joules of energy then?
I know this is old now but great tutorial, what size screw/bolt please?
Por favor haz un vídeo cambiando la válvula de CO2 . Gracias
my powermod for ~40joules .177 is one drillbit and custom made round out of .22 lr shell.
Does this work on dan wesson 715 4 inch
Hi David thank you for interesting video regarding in increasing the power of a CO pistol . Could the same mod be done to a Webly MK 6 CO revolver
Does anybody know where to get parts for these things at all.
Mine dumps the co2 out nearly instantly.
I cant find a replacement valve, or gasket kit anywhere.
Theres no numbers stamped on the valve, no nothing.
Any help would be appreciated.
Can you explain how to do the orther mods I.e Hammer sping and shells please
Will this also work on a crosman snr357?
They look extremely similar.
More power thru the cap? Interesting 😊
Sorry iv not been on for a while as been ill for a while,but will be putting my custom Daystate Midas when I'm finished it that is.
hi david is it the same principle with the umarex beretta co2
does this work on Ruger superhawk 8 co2 also ? :)
Hey there Mr Robinson can you please help me. I'm trying to increase the FPS on my Dan Wesson 8 inch revolver BB and I can't modify it due to its really, really tight screw. The last two that the handle covers are the ones that I'm having trouble with, which is kind of strange due to its size; I can bench press nearly 300 pounds ( so you can understand my frustrations), can you please tell me how I can unscrew them without damaging the gun or the screw?
can you tell me how the rifle barrel worked out thanks
How exactly does this increase the power?
My thoughts exactly. Just increases the hammer tension.
Hi, I have the 1 joule (downgraded) version of the 6" Wesson. Do you know the method the manufacturers "downgraded" the gun?
Is it with a weaker hammer spring, a stronger valve spring or would it be something else which limits the power (such as a smaller valve)??
if you have it in 6mm, those are low power shells, you can buy full power shells for a bout 1.50 each, this mod will also work with low power shells
+Onyx BlackScale Hi I also have a DW 6mm 6" marked with a 1 Joule label. How do I identify the Power down shells from the normal shells. I purchased extra Shells (with no power down labelling) but do not see the difference with the shells provided with the gun. Any idea how to distinguish between these shells
full power are a browny orange and low power are a yellow colour,
im not aware of any internal mods, mine with full power hits 440 low power 320 the low power just have a smaller gas flow hole
+Onyx BlackScale Hi thanks for the identification of the LP Shells. My gun came with the brown coloured shells I'm still bewildered as to why its labelled as 1 Joule. Would 1Joule of power with 6mm steel BB's achieve 440 FPS
+chinagongs On the shell colour, I assume your a referring to the plastic head of the shell?
is there anything else we can do as ive done that mod with not a lot of improvement just uses gas a lot quicker
how can i get one of those preassure pins? i just fkd up one of mine :'c
hi, I have a Dan Wesson CO2 6 inch 6mm BB pellets. you can upgrade it? if you like and where I can buy any spare parts? Thanks for all
an easy but very limited power upgrade due to the limitations of the transfer port and co2 pressure..
Hi,I'm not sure why it is lose but know that some are and I would take it back to the shop,but if that's not possible like mine as I striped them so mine was lose so I used plumbers tape on the back of the barrel but its tricky to do and used a very small amount of glue to keep it tight then put some in the pin holes then put pins in its been fine and had no problems,as there's not much you can do to make it fit better or be solid,that's the only bad thing about this gun.

I live in USA where there really aren’t limits on power of co2. I’d like to learn more about this subject
Thank you Dr Gunsmith
Excellent video, whens the next installment??.. May I please request your next video is also a revolver.... :P I am getting the 2.5mm next week... any further info on these guns is greatly appreciated
Porque no se traduce en español tengo una igual y me interesa la modificación
I'm looking to get the newer Dan wesson, 715 - 4" barrel.
Does anyone know of any good power mods for it??
Many thanks
Brilliant! Thank you so much. Subscribed.
Great idea. I suggest to polish te "front surface" of the screw an apply some grease on it, so the aluminium "cup" wount wear too fast. By the way..

AWESOME VIDEO BUD !!!!! 1.) HAVE YOU CONSIDERED BORING OUT THE INTERNALS OF CO2 VALVE TO HOLD MORE CO2 ? ,2.) ALSO MAYBE BORE OUT THE CO2 EXHAUST TUBE THAT FEEDS CO2 TO THE BARREL !
3.) AND ALSO , HAVE YOU EVER MODDED THE CROSMAN 357 REVOLVER ,IT HAS SO MUCH POTENTIAL !!!
Crossman gas revolver is deadly I once shot at a pigeon it exploded quite well 🤣
Perfect vid, thank you so much can u do one for the newer Dan Wesson 715 pellet version please
Excellent video mate. Can this be done to an umarex legend S60 as it's very similar to the Dan Wesson?
The only way to get more power is to change the valve to release more Co2
Bueno , y como se cambia la válvula ?!?
Exactly, I'm fed up with fake videos even more from a "gunsmith" who dosent if test the "Power mod" with a chronoghraph to show it worked
Great video and explanations! is there a possibility to put a gas canister that will be filled with air to turn it in to a pcp air gun? i'm thinking to replace the co2 cartridge and give it some more power. i have the ruger superhawk airsoft and i have replaced the inner barrel with a 60cm one(not for airsoft animore as it has too much speed) i use it for backyard target shooting
make the nozzle the same size as the co2 canister exactly and there
can we get this gun without a ukara ?
Hi mate if i travelled could you help me with. My Air Arms Prosport?
More Videos Sir. Where are you lost ?
Hi great video , can you advise how to power up a sig p226 pellet blow back close sub 6 lbs uk
is it possible to do a co2 leak fix videos for the dance weston
thanks bud, you sounds geordie? im from consett, and i see you have lots of extra cartridges, where would you advise me getting them? havnt actually bought the gun yet but ill need some extra cartridges.
I don't live that far from you mate I'min Durham,I bought my extra cartridges from ebay but not sure if they sell them now but if you just look on the Internet you will find loads that sell them,thanks for asking.
I whant do this to mine Ruger of Umarex its also a WG but its a 8 shooter instead of 6 and easy to load to,

I know this is an old post but I've found this very useful. I use mostly 6mm airsoft replicas and I'll try using this method to actually lower the fps in my Co2 revolvers.
Do you know if other wingun revolvers have similar internals?
Nice video.
Do you know how to fix a leaking Dan Wesson revolver?... I applied silicone oil on the Co2 seal but didn't work.
you gotta find the valve somewhere. I only know magazine operated airguns have this valve to tighten that i will use scissors or thin pliers since they key you have to buy.
Size of the bolt?
