Built to the same standard as the barrel extensions we use on our 6ARC barrels, the KI Precision AR-15 Barrel Extensions are designed for serious builders and gunsmiths who demand strength, consistency, and reliable feeding.
Each extension is precision machined from 4140 hardened steel rod for excellent strength and durability. The feed ramp geometry is designed for reliable cartridge presentation and smooth feeding.

Whether you’re building a custom AR-15 or replacing an existing barrel extension, KI Precision AR-15 Barrel Extensions give you the same proven extension design we trust on our KI 6 ARC barrels.
