m100 makes my m4 go 380fps

[kevshin21]

hey guys I gotta question, My m4 has full upgrades (the works) and its shooting too hot witha m120, so in order to let me play cqb i need to water it down to 350 fps. My problem is that a m100/110 was installed on it and its still shooting 380! what do i do now? currently i just put back the stock spring which shoots around 300

[farewell_red]

I know this isn't quite the advice you're looking for, but 300 fps is plenty for CQB, and will only make things safer for those on the receiving end.

[Md0ggyd0g]

Did you break the new spring in (yes, a simple question but sometimes people are too anxious to start shooting again).

 

Other than that maybe take off the TB (assuming you have one) for CQB, since it's not really needed.

Try a 1J/M90 spring

[Xaccers]

Try turning the spring around, that can drop fps a bit.

If you've got a bearing piston head and spring guide, replace the spring guide with a stock one.

[Stealthbomber]

If you've got a fully upgraded gun then your best bet would be to leave it set up for woodland and buy another gun for CQB.

You'll wear stuff out, strip screws, lose/break parts and get it more dirty, by continually swapping the springs.

 

Unless it's an ICS or Systema M4 that is.

What about the Tokyo Marui Muzzle Velocity Reduction Adaptor?

 

That may work...

[[BS]_MARS]

A velocity reducer keeps all the stress of a higher spring while shooing lower. Just go to a m90.

[poorieuser]

Why'd you upgrade it so much if it was for CQB? Aren't most Stock CQB guns right around 300-330fps?

[sirrith]

maybe because it wasnt used for CQB when he upgraded it the first time

 

try a KA m110

or if you have a tightbore, try a KA m100

or you could go for a PDI 120%

[kevshin21]

yea it was for woodland at first. But since good places are closed and a cqb area is close to be I have no choice. I have been thinking about getting another gun though but we will see, and sirrith I do have a tightbore and tried a KA m100 it shot 380...

 

 

edit: also the TM reducer is not allowed in cqb area beacuse its not effective in full auto fire.

[squeeky]

Whats a m100/110? never knew springs come in fractions. But anyways...find out exactly what spring you have, including the company that makes it. Then come back and ask again. Systema m100, KA m100, KA m110, Prometheus ms100sp, Prometheus ms110sp, guarder sp100 all shoot at different velocities ranging between 336-387fps.

[sirrith]

so its shooting 380 with both the KA m110 and the KA m100?

 

mispackaged spring perhaps?

try a guarder SP90 then, thats cheaper than buying another gun, and at least you'll have more power options in the future

[kevshin21]

do you guys think i should just stick back the 400 fps spring back in and get the x-factor s-system for cqb? you know the MPEG from the TM copies thread?

[sirrith]

if you have the money, i dont see why not

[Tommygunn]

My Systema 1J spring gives me a perfect 328fps.

M100 aren't universal, for example Guarder springs are very powerful for their ratings, I had an M15 give out 3*0 with a Guarder SP100, and my mates G3 is doing the same. Prometheus springs are weaker I find, try a Prometheus MS100, also are you using a bearing spring guide/piston head? If you're still too hot replace the bearing in the piston head with a washer and screw.

I think we already covered that.
