I shot my recently built Grendel today to function test it. It has a cut down 24" AR Stoner bbl and Bolt. It's a rifle length gas system with a Syrac adj gas block. I have a Magpul rifle stock and a Noveske 13.5 NSR holding it together.
Absolutely no function problems except the $100 dollar adj gas block seems to be letting some gas out the adjustment screw. I'll post pics shortly, but has anyone had this problem?
