After building several AR15's with no problems, I decided to build an AR10. Purchased stripped upper and stripped lower and bolt carrier group from PSA. Barrel and parts kit from Surplus Ammo. Went to test fire and first two rounds where fine. Pulled the trigger on the 3rd round and it stove piped. Cleared it closed the bolt and it didn't stove pipe but didn't go al the way into battery. Forward assist didn't help. Tried to eject the round and bolt was stuck. Got it cleared with some work and very next shot did the same thing. Pulled the gun apart and figured it was too dry. Pulled the BCG apart cleaned real good lubed real good and it cycle a little better but still jammed up. Noticed it was really jacking the rounds up. Used to different PMags.
Anyone got an idea where I should look next?
