The Superlative Arms AR-15 Direct Impingement Bolt Carrier Left Hand Black is a purpose-built carrier designed for shooters running left-handed AR-15 uppers. Machined from 8620 steel with a mil-spec chrome-lined bore and dark diamond-like coating, it delivers smooth cycling, reduced friction, and easier cleaning while remaining compatible with any standard AR-15 bolt.

This left-hand DI carrier is ideal for upgrading an existing rifle or completing a premium build focused on reliability and long-term durability. Its DLC-coated gas key is secured with Optimized Carrier Key Screws (OCKS) for excellent staking and screw retention, making it well suited for high round count range use, training, and general-purpose shooting. Superlative Arms’ in-house manufacturing and attention to detail provide a refined component that complements quality AR-15 platforms.
