KAK Industry Bolt Carrier Group For AR-15 8620 Steel Construction Chrome Lined Phosphate Finish Black C158 Bolt was the sixth most added bolt carrier group on GunPartPicker in October 2026, behind the Sons of Liberty Gun Works AR-15 5.56 Bolt Carrier Group 158 Carpenter Sp/HPT/MPI, with about 2% of all bolt carrier groups added to builds. Up from #67 in September. Builds with this bolt carrier group are nearly all chambered in 5.56 NATO, mostly on mid-length gas (86%, then carbine-length 12%), and nearly all AR-15.
It was hard to find in October 2026, in stock on only 10 of the 27 days we checked, and today none of the 2 retailers we track has it in stock right now.
