AR-15 10″ Pistol Brace Build Kit With Milspec Buffer Tube (Anodized Royal Purple)

Description

This AR-15 pistol build kit delivers a complete furniture set in Anodized Royal Purple, engineered for builders assembling a 5.56 Caliber AR pistol platform. The package combines a Milspec Buffer Tube assembly, skeletonized pistol grip, and 10-inch M-LOK handguard — all machined from T6 aluminium and finished in the same anodized purple coating for a unified appearance.

The buffer tube kit is built to Mil Spec dimensions for compatibility with SBA Tactical braces and similar stabilising devices. It includes a six-position buffer tube, castle nut, end plate, 3 oz stainless steel carbine buffer, and chrome silicon spring. The assembly weighs 9.6 oz complete. The tube’s Mil Spec threading ensures it accepts standard commercial braces without adapter hardware.

The skeletonized pistol grip belongs to the Ultralight Series, reducing weight to 3.6 oz through oval cutouts while maintaining structural rigidity in the T6 aluminium body. Ergonomic finger grooves run along the front strap, and the grip’s profile is designed to position the trigger finger perpendicular to the trigger face during the pull. The cutout pattern removes material without compromising the grip-to-receiver interface or the through-bolt seat.

The handguard is a 10-inch free-floating M-LOK rail system that slides over the proprietary barrel nut and locks to the upper receiver with six screws. The design creates a continuous top rail from receiver to handguard end — a near-monolithic rail platform. The internal diameter measures 1.34 inches, accommodating standard AR-15 barrel profiles, and the M-LOK slots on the 3, 6, and 9 o’clock positions accept KeyMod-compatible accessories. The handguard and barrel nut together weigh 7.9 oz. All three components are US-made and anodized in the same Royal Purple finish for colour consistency across the pistol build.
