The KAK Industry K15 is a complete AR-15 pattern pistol chambered for 5.56 NATO and compatible with .223 Remington ammunition. It features an 11.5-inch barrel, a billet aluminum lower receiver, and a 6061-T6 aluminum M-LOK upper with KAK Industry’s proprietary clamping system and heavy-duty barrel nut. The included one-piece bolt carrier group uses an aircraft-quality 8620 steel carrier with a Black Nitride finish, while the 8740 steel firing pin is precision ground and chrome plated. A billet enhanced extractor with a phosphate coating supports reliable extraction and corrosion resistance. The black hardcoat anodized billet lower is machined to military-spec internal dimensions and includes an M4/M16-spec fire-control pocket. With a 30+1 capacity and standard AR-15 controls, the K15 provides a compact, modular platform for recreational shooting and range use.
