Need to cut off 10fps

[LazzurusMan]

I changed the nozzle, cylinder head, piston, piston head, spring and short stroked, jumped from 340fps to about 360 on 2s. I need to shave off 10fps, would using the original non oring nozzle do it you think? The seal between cylinder head and nozzle was shocking, hence why I got the replacement parts. I didn't realise it would improve it that much.

would probably work or take a coil off the spring?

Try 'scragging' the spring first. You'll need a long bolt or threaded rod, a nut and some washers. Put the spring in and compress it to maximum, leave it for a day or so. You may well find that it drops that 10 fps.

Shouldn't work on a good spring but airsoft springs seem to be pretty shite from what I've seen so far.

Honestly, I'm gonna try the stock nozzle first as the one I bought is about .2mm longer, and seems to be causing some feeding issues too. 

Why can't manufaturers all agree on ONE length for the nozzle on a standard m4??

What 'M' rating spring have you got in there at the moment?

It's a guarder sp120 spring.

I ended up taking about a coil and a half off to get it to about 1.1 joules. bPerfromed beautifully on sunday, outraanging most of my team, including our dedicated sniper.

But according to them I shouldn't work on airsoft guns I "Don't know how they work".
