New Grendel, dreaded fail to feed

[sundowner]

I have a PSA 20"SS upper on a PSA lower , first question is where are your ejected rounds ending up whit you muzzle being 12 o'clock and you buttsock being 6 o'clock and you may have to open up your gas block . I had to upon mine up the adjuster is on the side and the locking set screw is in the front , You need a 1/16" hex tool to make the adjustment , I found one by MasterForce at Menard that looks like a small screwdriver .
