Great product... Buy it...


This BCG is great..... While I did not buy it here, Got it local from A*B Arms, it is good quality.... Nice staking on gas key, finish is still beautiful after a few thousand rounds, gas rings still doing their job well. The bolt itself is showing some discoloration but cleans up fine... If I were building another rifle I would be getting another one today.. You can keep your Fail Zero and your BCM's and your other "name brand" BCG's if you want. Shoot it, clean it, shoot it again and repeat..... A*B Arms... Veteran owned, Central Pennsylvania local....
