Up from #41 in September. Builds with this bolt carrier group are mostly chambered in 5.56 NATO (79%, then 300 Blackout 21%), nearly all on carbine-length gas, and nearly all AR-15.
It was in stock most days in September 2026, and today only Brownells has it in stock. Prices barely moved in September 2026, holding around $527.85, so there haven't been real sales lately. Buying today, the lowest price is $527.85 at Brownells, which matches the best price we saw in September.
