I have an Aero lower and upper that I will be using. RCA Bolt Carrier. What seems to be the consensus on making a 7.62 AR reliable? Which Barrel, bolt, and Magazine do I need to build it with. I have read some are miserably unreliable and others claim that they are super reliable. Thanks for any input from those who have built them.
