P90 Noise reduction

[BrokenBird]

I have a KS P90 and I really hate the sound of it, most likely because the gearbox is just where my ear is when I shoot it. So the question is what can I do to reduce the noise this baby does?

Thanks.

Wrap the battery in a sock.

Have the gearbox shimmed perfectly and the motor tuned to the optimal height and it will reduce the noise coming out of the gun.

I used to just put a plate and some cushioning against where the sounds was coming from

ARS POM Piston head
Double O-ring cylinder head w/ Sorbo tablet
Light weight piston
Prometheus double torque helical gears shimmed to perfection, G&P M140+ that's been run on a motor lathe to ensure the comm is perfectly round.
Kanzen universal bearings (the ceramic make more noise than the standard, but spin better)
Airseal nozzle, perfectly sealing hop-up system and rubber,
Non-linear spring
Rotary spring guide
Barrel to the end of the stock gun's barrel then an additional 5+ inches of silencer.

Dynamat or another type of adhesive noise reduction stuff on the inside of the body around the mechbox.

Yup, that just about cover all of it. And if after all this and it's still too loud, just don't plug in the battery..

I just tried my AK Silencer, and it already makes a BIG difference, thank you all.

get a cylinder head with sorbo pad's and shim your gears well and get a rotary modify spring guide vr. 3, basically what AMOS said.... That will silence your gearbox quite a bit. Goodluck

Get a G&P motor. I only had experience with the M160 but I think it's safe to assume that any G&P motor will sound nicer than the stock one.

Unless it's a TM motor, the EG700's are one of the quietest motors I've seen.

But the M140+ line is SUPER nice

I've got a 170 Devil Jet sitting in my G3 right now

How much more performance does the M170 offer over the M160? I can't imagine the types of springs you could pull with that kind of motor!

I saw a very noticeable increase in rate of fire. My G3 before was about 14BB/sec on a 120 spring, now its about 18-20

(I've got a torque setup, not a speed setup)
