I'm rather new to upgrading an AR - 15 so please bear with my question. I have a DPMS Oracle AR-15 that I was told I should Up-Grade my bolt carrier group because the standard factory BCG fails quickly. I'm looking at a Palmetto State Armory Full Auto Bolt Carrier Group because I'm also considering a Binary Trigger which requires the Full Auto BCG. Even if I don't add the Binary Trigger, What is the Advantage of a Full Auto BCG vs Standard BCG?
