Some initial observations:

1) the aluminum nozzle and steel bolt carrier combo is heavy and shows in the noticeably slower rate of fire.

2) aluminum nozzle fits well in the stock aluminum carrier ( with the steel guides). In fact, the nozzle moves more freely in there. I much prefer the overall performance in the stock aluminum carrier.

3) Clockwise turn of NPAS = more fps

4) don't open NPAS too wide (i.e dont turn all the way clockwise) or function will be impeded. Remember, gas must be able to flow behind the NPAS valve.

5) there appears to be a sweet spot for the NPAS where you can achieve very stable results. Mine is where it's set at 385 fps with .25g BBs. More testing needed tho.

6) aluminum nozzle works well in the M4 CQBR. Works really well in the 416.

I still need to fine tune the nozzle. I still must achieve my objectives of stable 360 fps on .20 and 400 fps on .20.
