Kak Industry
The Kak Industry M16 bolt carrier group for 7.62x39mm is built for shooters who need a reliable, no-nonsense AR platform component without the premium price tag. This chrome and phosphate finished BCG combines proven metallurgy with tight tolerances to deliver the dependability expected in a workhorse rifle part. Whether you're running an AK-pattern AR conversion, plinking, or building a budget-conscious 7.62x39 rifle, this carrier handles sustained fire and hard use with the kind of durability that doesn't require constant babying.
Every component in this bolt carrier group is purpose-selected for reliability and longevity. The carrier itself is machined from 8620 steel, heat treated and ground to exacting specs to handle the pressures of the cartridge. The billet-machined 4140 extractor is phosphate coated for corrosion resistance in field conditions, while the 4340 cam pin carries the same protective finish. The 8740 firing pin is chrome plated and precision ground to ensure consistent ignition shot after shot. Both the S7 tool steel ejector and extractor retaining pin, plus the 4130 gas key, are finished and staked to resist wear and maintain alignment through hundreds of rounds.
This is an M16 (full auto) profile carrier—the standard architecture that pairs seamlessly with most AR uppers and bolt assemblies. Kak Industry's attention to heat treatment, material selection, and finish choices means you get a part that resists corrosion, functions reliably in adverse conditions, and won't require replacement for a very long time. If you're assembling or upgrading a 7.62x39 AR and want a solid, proven BCG foundation, this is a legitimate option.
