I recently purchased a 'used' Aero AR10, built by Compass Lake. Looking at the barrel through the borescope leads me to believe the gun was only fired by CLE after assembly. The rifle was built in 2019, 1 of 3 for a single customer. The rifle is a joy to shoot. I've only 82 rounds through it, just starting load development. The basic specs are:
Aero enhanced upper
Aero lower
Aero black nitride BCG
20" Kreiger 10-twist barrel, .875" gas block journal
M118LR chamber
Adj gas block (I installed this)
PRS stock
VG6 Gamma muzzle brake (I installed this)
Geissele NM trigger, with light match springs
I've acquired 3 new LaRue magazines for the rifle but am having an issue with all of them. The 2nd to last round will not feed from the magazine, the bolt normally skips over the top of it or pushes it forward 3/4" then jumps over the case rim and jams into the body.
Is there a standard for the magazine feed lip spread or how much of the magazine should extend above the lower receiver?
I'm shooting reloads with COAL of 2.800". The feeding issue happens while; shooting from a loaded magazine, loading 2 rounds in the magazines and pulling back the charging handle or releasing the bolt, or slowly closing the action with the charging handle. Any guidance on determining root cause will be GREATLY appreciated.
