Hey Allout,
I got the M-4 with .20 @ 395-398, > .25 @ 370-375 > .30 @ 340-350 I adjusted the NPAS valve along with drilling 7/64 hole in side port. I'll post some pic up for you and other fellow GBBR.

That 7/64 hole was an bad idea, need to order another brass nozzle

how was it to install that NPAS ? i ordered one for my WE m4 4168 but im not sure how to install it...

it's pretty simple, Open your upper from lower reciever, then re move charging handle, now once the charging handle and internal barrel is out, Unscrew the valve from the guide rod, Do loose the spacer, take it off also, then take flat head screwdriver, to rear and remove bolt, follow by removing the rod, now putting in the NPAS valve is just the same, Use Silicone spray or lube for all orings you see, should be three total. Now adjustments Shot one or two shoots and check against an chrono, Open upper receiver and take special tool and small screwdriver, the speical tools goes down the center and use screwdriver to hold valve in place. Clockwise raises and counterclockwise lowers

so your talkin about the screw on the back of the bolt hold the everything in place? sorry for the late reply

That screw only keeps the pin from seperating. I will post pictures next week.

aight thanks!!

The Upper recievers should be here atleast by next monday before the 11th game, I am wanting to run my GBBR again
