AO is My New Favorite BCG April 10, 2018
Reviewer: Binary Beast Mode from RICHMOND, TX United States  
I ran this bolt with my Franklin Armory BFS3 and it worked like a champ. Me and my buddy first ran about 100rnds in semiauto, the we ran another 100rnds in binary mode just double tapping. Once we got my FN CHF Barrel good and hot, then we went "FullSemi Auto" LOL. We ran 300rds Full "binary mode" aka poormans FullyAuto. So a total of 500rnds and we did n'\ot have 1 failure of any kind. AO Precision BCG did not fail with that abuse. I will be buying much more
