I’ve not heard very brilliant things about angry gun but haven’t tried any of their parts personally, I’ve just been told by a few to stay clear, personally I love the g&p bolt carrier, not had any problems with it yet but as I say it does increase FPS quite considerably in my case so may need an npas to make it site legal
Others have found that it gives higher power.
I have used a RA Tech NPAS in a TM nozzle / bolt and found it pretty good at dropping the FPS. You need the black one, as the silver (WE) one is too fat to fit.
I would check what is in the G&P nozzle to start with as they might have used the 3 position valve stopper (or get one for £9 from Firesupport) as this can be used to alter the FPS too.
Awesome thank you buddy I’ll take apart the g&p and take a closer look at the parts inside, I don’t believe it has a valve stopper but I’ll take a look, can the valve stopper be adjusted to do the same job as an Npas?
