- The Nexus Pro is a handy blaster out of the box, but in the video I'll show you how I took its performance up to 250 fps and beyond with a simple expanded plunger tube mod.
The key piece is designed by Andrew Tran and is available here: drive.google.com/drive/folder...
I've also used tactical pieces designed by Chicken Creations available here: www.etsy.com/au/listing/85116...
And a top rail riser by BlasterTech available here: www.blastertech.com.au/Top_an...

A very simple install for a massive increase in FPS. Great build.
Absolutely! Thanks mate 😎
Mark 13 mod, 2021, Chris Scaramanga Cartaya did it first, check it out, he used fiberglass and epoxy to make the overcarry on the pusher, averages around 330 fps with a K27.
th-cam.com/video/pKE8dIKPwVc/w-d-xo.html started building it last may
Yea, but its good to mention this too.
Damn nice video! You need more exposure. Gonna post this on DBNB. Came here to see why my PM's were blowing up, not all can handbuilt and this is a good way to get there. This is a good aftermarket solution, mine is a handbuilt mod, not feasible for sale, more for battle and an 18" barrel helps on mine however its good to have it available for aftermarket, Cheers!
Thanks Chris, that means a lot.
I don't think that this would be as durable at very high spring-loads as your more reinforced build, but it's certainly a great option if you're aiming for 250 to maybe 300fps with relatively effort 😎
@@andrewg_nerfmods Definitely more obtainable to the general public.
Hey Brother, great video. I'm glad to see others taking the approach of increasing Plunger Volume for higher FPS. I'm adapting a Drain-Blaster Plunger System for my Longshot. My Target FPS is over 300. I'll keep you posted.
Nice one - it's always fun getting different systems to work in different shells 😎
Did this build a few months ago, it's really great. Took some tweaking on the seals but the shell cutting was easier than I expected
Yes, definitely easier than I thought it would be 👍🏻
That's awesome! Hope to see more of those on the field!
Thanks mate - it really makes it so easy to get Longshot level performance out of a Retaliator sized blaster 😎
You honestly deserve more subs, your videos are great and easy to follow :)
Thank you - tell your friends 😎
Sweet, I'll have to give this a try soon.
Awesome mod!
Thanks mate - it's a great set of files that Andrew T has put together - works just as well with the Max Stryker too 😎
Excellent mod!
Thanks mate - Andrew's files make it easy 😁
Crazy performance, minimum complications, amazing.
Absolutely!
Awesome video as usual and a great blaster build. We are sourcing the plunger tube now. Andrew what do the other files in the Google drive for this build
There's a replacement breech piece - I found that this held the barrel too close to the pusher to seal properly (17/32" brass - may not be a problem with a Worker or MM barrel where there is a wider opening for the dart).
Some other tacticool pieces that might be fun - I liked the Chicken pieces that I'd already bought.
Can't wait to see what you do with a Jurassic Pro. They have that huge PT.
I think it'll be a long time before i get my hands on one of those...
But my initial thoughts are can I fit a small HPA bottle into that stock?
@@andrewg_nerfmods surely you could. It's perfect for it lol.
😁 we'll see...
Hey Andrew, amazing build, once again. Just a Q about the specifics.
How long(cm) are your 1.8 and 1.5 springs cut to?
Thanks mate - I don't think I took too much off that one - it might be 10.5 or 11 inches. I recall the full length had a fair bit more pre-compression, which I wanted to reduce somewhat.
No reason you couldn't use the full length, or even thicker springs, to go for more fps 😉
@@andrewg_nerfmods Thanks a ton.
very nice! whats the scope that you used during the grouping test?
Novritsch 1-4X scope / RDS: eu.novritsch.com/product/1-4x-variable-scope/
A bit of overkill at that range, but still fun to use 😁
hello from mexico. NICE JOB. Just broke my breach of my nexus and finally found the 3d piece. ONE cuestione. What are the other files on the link designed by Andrew Tran FOR?
Thank you 😀
The other parts are optional, but maybe be useful if you need a replacement breech or plunger head etc. There are also pieces to help lock a barrel into the front of the blaster, to replace the original collar piece.
@@andrewg_nerfmods excelent! tanks for that extra!
and for the tutorial
Hey Andrew another banger of a mod guide! Does the plunger tube dimensions and plunger head 3d printed part work on the max stryker as well? if not, what extra has to be done? also what is the best size barrel to fire adventure force waffle tip darts from the max stryker? Looking for aluminum size.
Thanks mate 😃 I see no reason that this printed piece and the tube wouldn't fit in a MS - there might be slight differences in where the shell needs to be cut inside, but overall it should drop in just the same I believe.
I would not recommend waffles in blasters with this one of tight breech / barrel - the fatter heads will just have to much friction, and possible not even load smoothly into the breech. I'd stick with Pro or Max or Worker short darts.
@@andrewg_nerfmods jeesus talk about fast reply.. TYSM andrew I will definitely stick to af pros and dart zone short darts! Also that barrel is preettty sweet where did you buy it?
A+ customer service 😆
This barrel I made myself, out of 17/32" brass glued into 16mm aluminium. You could just use brass with a printed spacer at either end, or wrapped in electrical tape etc. Or use a Monkee Mods barrel, or 13mm ID alu.
@@andrewg_nerfmods ah sweet thanks andrew!
Nice build! What kind of o rings should I use? There are a lot of them :S
Thanks 😎
O rings are usually described with inner diameter and ring thickness. If you need 36mm outer thickness (because that's the inner diameter of the plunger tube) then 32mm and 2mm or 31mm and 2.5mm will give you this.
When you pull the grip, it does not go all the way back?
@@LiveMusicRec It goes all the way back to where the plunger catches in the original configuration.
Quick question, are all the screws in the nexus pro the same length, or are there different length screws for different holes?
Quick answer off the top of my head - I'm 95% sure they're the same, and want to say m2.6 10mm length. Or maybe 12mm.
But 12mm seems a little long for thin parts like the buffer tube and secret screw under the grip - I may have used 8mm ones there.
Hey. curious if this would work in a stryker. I figure it would but you can never be too sure. Also, I cant find that diamter of plunger tube anywhere. Do you now of anywhere? Lastly, is there anywhere i can find the parts in the description pre-printed? Thanks!
Yes, will definitely work in a MS - I know of people who have done this.
I got my tube on Ali Express - can see polycarb, acrylic & even stainless steel options in the right diameter there now.
And no, I'm not aware of anyone selling the parts ready printed. Maybe you could ask around your local group to see if anyone could help you with printing?
I've also read 10" is superior to the 8" and 12" lengths for max fps.
Any plans to get the fps higher than it is on your Max stryker?
The right length also depends on the darts you use and where you are located (eg temp & humidity have effects) - there's really no "best" length that will suit everybody, everywhere.
I could use a thicker spring (2.0 mm) or a bit of extra length or pre-compression for more fps, but that's not really a priority for me. I'll be using HPA blasters at our local events with high fps caps anyway, so I do mods like this mostly out of interest 😁
great video! anywhere for us chumps with no 3d printers to buy the expanded plunger tube mod parts?
I don't have a printer myself, but a mate in my local group does little bits and pieces for me now and then.
There are plenty of businesses that print your designs (for a fee, of course), or sometimes places like public libraries have printing services available.
Nice build, what kind of screws did you use?. They look different
I replace the screws on nearly all my mods with hex head (socket cap) screws. No more worrying about stripped screws for me!
Most blasters use M2.6, though some need M3. The length varies - these are 10mm.
I buy from eBay - takes a while to get here from China, but I've got a good range of sizes on hand for most things now.
also, could an 11 inch spring work you think? or would it be too small.
It would be close - if it was a fraction too short then you'd just have a bit of slop in the prime - easy enough to pop a spacer in to remove this.
Would a schedule 40 pvc pipe in the same dimensions work also or is acrylic less brittle than pvc to handle the air pressure better?
I think acrylic is more brittle, tbh. The material won't really matter - PVC with the same dimensions (or near enough to get a good seal at both ends) should work just as well. Polycarb is another option 👍🏻
@@andrewg_nerfmods Thanks.
Also what would you say would keep the numbers consistent?
Clean barrel & consistent darts I reckon
How hard is it to prime that 1.8 spring? is it manageable for a weakling like me lol?
I'm a bit of a weakling too - the big spring is a bit of an effort for me, and I'd need a break from this every few rounds!
So the spring is 15 mm diameter, 300 mm length, and 1.8 mm thick. The tube is 40 mm OD, 36 mm ID, 105 mm long, 2 mm thick. What is the best Oring for the ram?
I used an o-ring from another Nexus Pro that didn't need it, so it's the same as the plunger. You'll want the OD of these to be 36mm - I know that these are usually described with ID & thickness, so maybe 32mm inside & 2mm? Or 33 & 1.5?
Will this work with the max Stryker as well?
Yes indeed - internals are the same (at least for plunger tube & pusher geometry) so you can definitely do this mod on the MS - I know people who have done just that 😎
Awesome video! What kind of range are you hitting with that? I think the furthest my 180 fps one does is 30 maybe 40 metres
Thanks mate 👍🏻 Honestly I haven't tested total range - 250 fps should go 50-60 metres I reckon. A stronger spring taking you to 300 fps and above would go even further than that 😎
@@andrewg_nerfmods hey mate! I followed your instructions and have installed my first brass barrel! First 20 shots were beyond amazing I was able to hit my neighbours gate across the road from my porch, only issue is now I'm getting consistent squib loads, any advice as to where I may have stuffed up or something I should tweak would be much appreciated 🙏
Check for air seal - if something isn't sealing right then that could explain what you're seeing.
@@andrewg_nerfmods I just finished messing around with the seal and taking it apart several times which was a fun process haha, I can cover the muzzle with my hand and it holds pretty decently. I'd say maximum 7-10 seconds if that helps. It fires with decent fps with the occasional squib. They all seem to stop at the same spot on the end of the barrel maximum 5 cm deep. do you think it would be worth cutting the barrel shorter?
That seal sounds pretty good. What barrel do you have (length & material)?
nice build, can i ask what kind of tube did you use on that plunger tube? and also the size.. thinking of doin the same build coz its freakn' ccoool👌🏻.
Thanks mate. I used 36mm ID / 40mm OD polycarb, but after a while this developed a crack. So then I tried acrylic, same dimensions.
Stainless steel would be another option.
105mm length was just right.
@@andrewg_nerfmods nice, thankzz for the details...
@@andrewg_nerfmods another thing bro, is the 3D printed part from the pusher is a free source? can i ask for the file?... thank you👌🏻
@@franco8190 That's the link to Andrew Tran's Google drive in the description
@@andrewg_nerfmods noiceeee...👌🏻
Is the stock spring too long or too short to work in this mod, im a bit confused. Did you cut down that 300 mm spring? if so how long was it when it went into the blaster?
Yeah because the front of your plunger sits further forward without the telescoping bit, the stock spring is too short and will rattle about.
Does this same kit work in a Max Stryker?
I see no reason why not - I think I'll try this on my MS soon 😎
Hey Andrew, do you know of anyone who can reliably 3d print these pieces? I would like to do the same to my Max Stryker but do not have a 3d printer readily available.
Edit: Also, what kind of silicon padding are you using on the end of your plunger head?
What's your location?
The silicone was from a Worker spring upgrade kit for something - just had it floating around in a box of stuff. You could probably find something in the plumbing section at Bunnings that would do just as well.
@@andrewg_nerfmods I have a USA location, and understood on that second part!
@@jacoblewis437 I reckon see if there is a nerf group somewhere nearby - good chance you'll find someone who can help.
Alternatively, maybe asking for help on a FB group might find assistance for a reasonable cost of filament plus postage.
would that work with an out of darts skinny pusher?
There is a reinforcing part that runs along the top edge of the pusher. It's not particularly thick, but worth checking to see if it's not wider than the rest of the skinny pusher.
Alternatively, you could combine both designs into one - that's probably a more stable solution 😎
@@andrewg_nerfmods ive got minimal mod experience
can I get the links to the stuff you're using such as the spring and stuff?
The printed pieces are in Andrew Tran's Google doc folder in the description. For the spring, I got several from Ali Express - you can find a range of these all 305mm long - I measured the inner and outer diameter of the stock spring and used this to ensure that they fit.
@@andrewg_nerfmods okay ty
5:35 trigger
What happens if you use 175fps spring cap?
I think that the stock spring might still be loose, or at least have no pre-compression. My thinking is that you'd get better results with a longer spring, making use of the additional priming length.
Is the double prime lock still functional
I know I left it in, but I don't think it actually locks anymore due to the shape of the printed piece over the top of the bolt.
So no, not functional 😎
@@andrewg_nerfmods I was able to get the priming lock to work by removing a small amount of material from the top of the long piece of the ram, just enough to make the prime lock still functional while not weakening the pivot point contact.
this part is called the PTHead in the fileset?
or ram?
Yep - it's the XPT Ram piece 😎
@@andrewg_nerfmods how about the tube dimensions,what's the OD and how long should I cut to ensure optimal efficiency
105mm long - 36mm ID / 40mm OD.
@@andrewg_nerfmods does it have to be super precise?I found a ID of 38mm OD40mm one can I just make the O ring thicker to compensate?
Link to plunger tube?
I found on Ali - just search for acrylic or polycarb tube, 40mm OD / 36mm ID.
(I generally don't post links to Ali or eBay, as they may change over time, and not be the best source depending on where a person is in the world.)
@@andrewg_nerfmods Thanks. Can you expand on the Oring used on the 3dprinted part? Which part is it from?
That was taken from another NP I've got which doesn't need a plunger 😉
Nice video mate, better than Bradley Phillips videos by a mile! Have liked and sub"d you! Keep up the good work!
Hey Mate just found your channel. keep up the good work :) I will be doing this upgrade shortly :)
Any chance you can link all the parts ie. springs and tube. I am completely new to the hobby and would just like to click buy now :)
Thanks mate, glad you enjoy 😎
Reach out if you need any further details 👍🏻
@@andrewg_nerfmods Any chance you can link all the parts ie. springs and tube. I am completely new to the hobby and would just like to click buy now :)
@@AussieFirebird Other than the 3D printed pieces linked in the description, it's really only the plunger tube that you need to source. I got mine from Ali Express, but don't usually include links for these as they can change over time.
@@AussieFirebird 36mm ID / 40mm OD should do the job - acrylic or polycarb, or even stainless steel if you like 😎
@@andrewg_nerfmods Cheers mate
