Hi, guys ,I am having some issues with my Dominion Arms AR15.
Mine has Magpul BAD level installed, it has a CQ-A upper reciever with 13.5 YHM rails and low profile gas block. All lower receiver internal parts are originally parts.
Issue 1:
Bolt won't lock open after last round. This happens a lot especially with PMAGS, and it also happens on LAR15 or standard mags but less. I can engage the bolt catch into lock position by hand with any mags, and seems nothing is blocking the bolt catch. I will do some test next time with MAGPUL BAD level removed to see if it makes a difference.
Issue 2:
When the bolt does locked back(most of time by hand), release the bolt always result to some kind of jam, either the bolt is stopped half way by the first round sitting in a 45 degree angle, or the bolt just went over the first round and close the chamber with nothing inside and leaves a scratch/dent on the first round. I have to use charging handle every time after each reload. However as long as the first round is chambered, I haven't experience any Jam during weapon cycling.
Issue 3:
The brass extraction direction is very inconsistent, first round is always tossed at 4 o'clock and then last round is always tossed at 2 o'clock, is this normal?
What direction should I look into to solve the above issues? Thank you guys.
