Luth-AR BL-06LW A1 Compensator Lock Washer - 5.56/.223 AR-15

The Luth-AR BL-06LW is the factory A1 Compensator Lock Washer designed to seat and retain an A1-style compensator on an AR-15 lightweight barrel chambered in .223 Remington or 5.56x45mm NATO. The "LW" suffix identifies this washer as the lightweight-barrel variant of the BL-06 lock washer.

A correctly indexed and torqued A1 compensator needs the matching lock washer to hold timing against the barrel shoulder and resist backing off under recoil. This direct-fit Luth-AR replacement keeps the compensator properly seated so point of impact stays consistent across magazine changes. Luth-AR builds a deep catalog of AR-platform accessories, replacement parts, and armorer tools for builders and gunsmiths, and the BL-06LW is a small but essential piece of that lineup.

Sold as a single washer.
