PSA Gen2 KS-47 16" Carbine-Length 7.62x39mm 13.5" Lightweight M-LOK Nitride Upper With BCG & CH

Upper: The KS-47 G2 upper receiver is precision machined out of forged 7075 T6 aluminum, and then hard coat anodized for durability. While retaining the look of a standard M4 upper, the KS-47 G2 upper is designed to work with the new Gen2 KS-47 lower.  The upper features integrated over-insertion tabs to prevent the bolt from dragging on the magazine. This CMV 4150 barrel is chambered in 7.62x39 with a 1 in 10 twist and has a single, large feed ramp to accommodate the larger case diameter of the 7.62x39 round. The barrel is nitride treated for accuracy and durability, and is finished off with a 5/8-24 thread A2-style compensator. The forward assist, dust cover, charging handle, and safety are all standard AR-15.  This KS-47 G2 upper is finished off with a PSA 13.5" Lightweight M-Lok Free Float Rail. The KS-47 G2 upper will not work with a standard AR-15 lower.
BCG: The KS-47 Bolt carrier group is designed to work with AK-47 magazines, and features an extended firing pin. The carrier is made of nitride treated 8620 steel, and the gas key is attached with grade 8 bolts and properly staked. The bolt has been redesigned to function properly with most AK-47 magazines. The bolt is nitride treated 9130 steel.
