Chris Trivane at Replay Airsoft examines the variable in choosing the proper spring for AEG gearboxes. See our results at replayairsoft.com/airsoft-spring-guide
This is such a good video. This guy is definitely a teacher. Very informative but very concise. I watched several other videos and I think this one can be understood even by a person that has not much experience with airsoft. Great job
As I didn't see it mentioned, the 100 part of the m100 is a reference to the bb speed in m/s. Of course other factors can influence it and the springs don't appear to be all that consistent but that's why your results align fairly well with your research. You also should mention the cylinder to barrel ratio as that could be driving your change in results with regard to length.
Another thing to know about longer barrels is that as you go up and wait the power of your shot goes down because it drops your FPS even more than normally would. I gave you an example. If I were to shoot a 25 and a 36 I have my SR25 they would get about the same power. My interview is 450 mm. However, what I was trying to do was shoot 4 fives out of it and my sr25 currently shoots 1.65 joulrs but on a 45 it will shoot 1.45. I asked you need to take 50 mm more off the inner barrel.for .4's in a sr25 no more than 430mm for maximum performance. For .45 youbwant 400mm . You can even try And m4a1 in a barrel which should be 363 mm. I have an ak-47 length. Inner barrel And before you ask what the diameter barrel I was using, I was using a 6.01 to help with the the cylinder to barrel volume ratio, although it didn't really do a whole lot.
Awesome video! Im getting more and more into Tech work to the point where some friends have asked me to get their airsoft rifles tuned up. I just recently finished adjusting the power for my 3 vietnam-era rifles and found i had a spring that was WAY overpowered in all 3 rifles. I honestly have no clue what powerit is (my guess is either an M120 or M130). Im definitely going to create a set up with the fish scale to test unknown springs. Might not be perfect but there seems to be a measureable difference. Thanks for the video, ill be refering back to this one regularly!
super interesting, appreciate your methodic approach to this things! an odd detail that for my setups I get 415~ on m120 and 520 on m130, on a 500mm .01 inner, I use matrix brand, would they be mis labeled?
NO, your right on point. tight bore barrels will get you higher velocities. Also keep in mind there are other factors ie pistons, o-rings, cylinders , heads etc...
I got a brand new m4 and ibwasgetting 420 ootb and i ordered the 310 fps version. It also only has a 300mm barrel with a 6.04 bore diameter. then put a prometheus bucking in making the air seal even better because when i put the m100 spring in it the fps was get this 425 so it changed nothing at all. As a side note newer qc springs only require you to remove the stock.
So if I put an m130 spring in my matrix warlord modular to get higher fps (completely stock did not even open the gun up yet) do you think it would have no difference than putting the m120? I'm new to upgrading riffles and you seemed techy enough to ask
@@CRUC1F13D_13under normal circumstances a m120 is ,400 fps and m130 is what my m4 was doing before I shirt stroked. Now it's cqb legal and I'm thinking about taking 1 more tooth and putting 13:1 gears in it to up the trigger response. When you upgrade the trigger response you need a m110 and has the rates of fire goes up so does the power of your spring because you're pissing needs to return faster.
Did you say what BB weight was used for testing? Also, 200mm vs 500mm should have higher differences with heavier BBs, as they're harder to accelerate(but also harder to slow).
Ok so I have a 455 mm 6.03 madbull black python barrel. I want to run right around 350 for my normal riflemen requirements and maybe bump it to 400 if I decide to do a low fps dmr. What springs would I need?
I just put a shs m130 with a 6.03 380mm barrel IM CRAZY SHOCKED average is 495fps, low end was 485 maximum 502fps. Going of your numbers my spring should be m170 for the power I'm getting. Gun is a cyma cm518 (was lol) it has full shs gearbox, piston, cylinder 16:1, m130 spring. Stock motor is pulling it with a 11.v battery
Where do you think the best place for me to find a version 2 extended gearbox spring, I think it's just longer than a normal spring but I can't find any
You have a severe compression problem if those are the results. A m120 with excellent compression will yield 400-445. Just saying. There is much more to it.
Also it is very nice to have a quick change gear box and spring mechanism

This is a super useful and helpful video. Thanks so much for making this, I'll definitely reference it at work

You had me at your "build back better" comment. Liked and subscribed. Great info!
Thank you for the time and effort it took you to make this helpful video.
Thank u sir for sharing...this is very informative....very good help to understand the performance of an aegr....

Really good video. Thank you.
Great Video! Thank you very much!
Such a Good video with results.
Great info thanks 👍
Most useful video I've seen so far, Off to buy a m110 then
long barrel can cause issue. when you fast shoot your piston can make under pressure when it return to his position
What weight BB did you use during testing?
This is really helpful

dude all the info in this vid is a gold mine fr. my only ask is if you could recommend some good motors in comparison to the springs.
I just put a shs m130 with a 6.03 380mm barrel IM CRAZY SHOCKED average is 495fps, low end was 485 maximum 502fps. Going of your numbers my spring should be m170 for the power I'm getting.
Gun is a cyma cm518 (was lol) it has full shs gearbox, piston, cylinder 16:1, m130 spring. Stock motor is pulling it with a 11.v battery
Noice, I have bought a smaller spring specifically so that I can play at Replay airsoft
Where i live the limitation is by Joules, where in this video talks about joules?
Good video, gonna get a correct spring for my springer pistol
What bb did you used for this tests?
Heavy springs are thicker so with calibers you can determine what spring it is ball park...
absolute Peng genius innit
Where do you think the best place for me to find a version 2 extended gearbox spring, I think it's just longer than a normal spring but I can't find any
what is the different in the M120 o SP120 ? thanks
What type of BBs were used?
Quick and urgent question: is M110 spring with 0.20g BB okay for distance? (platform: SRC SR4 SD)
0.2 bbs are horrible for distance, use minimum 0.25
what gearset ratio have you used in this entire video what gearratio(s) ? in this whole vid 11:17
i took a screenshot on 13:03 and what gear is it inside, is it 16:1 or 18:1 ?? please help me thnks mwahh
Good day, if going for M140-150, which motor should i install with my AEG rifle?
Any reliable high torque motor. Element, shs or military does the job.
What about the thickness???
Mine is 510mm tight barrel , the spring is 140 & only 400fps. 😢
👍
what gram bbs?
Ok let's say I have some of these... what are the odds that a generic plastic gear aeg handle anything higher than 70m?
Asg M95 for cqb and asg m115 Maple leaf Omaga nub and bucking. A tion army or maple leaf berral .40k motor My set ups
Soo I wanted to put a m160 on my stock sr25 is that bad 👎
Replace your bearings with bushings, shimmed and high torque motor.
⭐⭐⭐⭐⭐
You have a severe compression problem if those are the results. A m120 with excellent compression will yield 400-445. Just saying. There is much more to it.
So you're saying if I got a 509mm barrel it wouldn't be as accurate as a 500mm barrel
