PolyTech Chinese AK-47 Complete Barrel Installation & Sight Component Kit

Whether pressing in a new barrel, completing a parts kit, or de-banning a Chinese sporter rifle, the PolyTech Chinese AK-47 Barrel Installation Kit delivers the factory-original hardware required for barrel assembly and front/rear sight installation. Sourcing small individual pins, detents, and leaf springs for Chinese-pattern rifles is often difficult; this comprehensive, factory-sealed kit packages every high-demand barrel mounting component into a single bundle.

Engineered to exact Chinese ordnance specifications, these parts fit Chinese-profile barrels—including PolyTech AKS-762, PolyTech Legend, Norinco Type 56, and Mak-90 variants. Each component is machined from heat-treated carbon steel with period-correct blued and phosphate finishes to guarantee exact fitment without hand-filing.
