AR-15 4″ Pistol Pistol Brace Build Kit With Milspec Buffer Tube (Anodized Royal Purple)

Description

This Anodized Royal Purple pistol build kit equips AR-15 builders with three essential components for completing a pistol-length platform in 5.56 Caliber. The kit includes a 4-inch M-LOK handguard, a skeletonized pistol grip, and a six-position buffer tube assembly — all finished in a matching purple anodize.

The handguard is machined from T6 Aluminum, weighs 6.2 oz including the barrel nut, and uses a proprietary barrel nut that clamps against the receiver with six screws. The tight receiver fit creates a monolithic top rail alignment, and the 1.34-inch internal diameter accommodates most standard barrel profiles. M-LOK slots run the length of the handguard for mounting lights, grips, or other accessories.

The pistol grip is also T6 Aluminum, anodized in the same purple finish, and features a skeletonized cutout design that brings the weight down to 3.6 oz. Ergonomic finger grooves provide a secure hold, and the reduced width is designed to enhance trigger reach and pull angle. Both the handguard and grip are made in the USA.

The buffer tube kit is built to Mil Spec dimensions and is compatible with SBA Tactical braces. It includes a six-position buffer tube, end plate, castle nut, a 3 oz stainless steel carbine buffer, and a chrome silicon coated spring. The complete assembly weighs 9.6 oz and is finished in the same Anodized Royal Purple. The tube itself is T6 Aluminum, and the included hardware is ready for immediate installation.

Total kit weight across all three components is under one pound, making it a lightweight option for builders working on pistol-length AR-15 platforms. The uniform purple anodize across all parts provides a cohesive appearance.
