A1 Slick Side Retro Complete Upper Barrel Assembly

This A1 Slick-Side Retro Complete Upper Barrel Assembly blends timeless design with modern performance for the discerning enthusiast. It features a 20″ 1-7 twist, chrome-lined barrel for superior accuracy and durability, with a manganese phosphate finish that resists corrosion while maintaining a period-correct appearance.

The barrel is paired with a front sight base (FSB), (.625″ diameter) and non-F marked for historical authenticity. The triangular A1 charging handle adds to the classic profile, giving you a smooth and efficient cycling experience every time.

The A1 hand guard not only preserves the traditional look, but maintains historical accuracy utilizing rivets to attach the heat shield for heat dissipation and a firm grip. At the front end, you’ll find the early A1 duckbill flash hider, a distinctive feature that reduces muzzle flash while maintaining a low-profile design.
