AR-15 9″ Pistol Brace Build Kit With Milspec Buffer Tube (Anodized Royal Purple)

Description

This AR-15 9-inch pistol brace build kit delivers the core furniture and buffer system for a compact 5.56 caliber pistol build, finished in Anodized Royal Purple. The kit includes a proprietary free-float handguard, skeletonized pistol grip, and a Milspec Buffer Tube assembly compatible with SB Tactical braces. Each component is machined from T6 aluminum and carries the same anodized purple finish, giving the build a unified appearance without requiring separate colour-matched parts.

The 9-inch M-LOK handguard uses a proprietary barrel nut and locks against the receiver with six screws, creating a tight fit that produces a continuous top rail. The handguard weighs 7.9 oz including the barrel nut and has an internal diameter of 1.34 inches, accommodating most pistol-length gas systems and standard barrel profiles. The M-LOK slots along the sides and bottom accept direct-attach accessories without adding rail segments.

The pistol grip is a skeletonized design from the Ultralight series, cut with finger grooves and a reduced-material profile that brings the weight to 3.6 oz. The grip width is sized to enhance trigger reach, and the cutouts reduce bulk without compromising structural rigidity. All edges are machined and anodized, with no sharp transitions where the cutouts meet the frame.

The buffer tube kit is built to Mil Spec dimensions and includes a six-position buffer tube, end plate, castle nut, 3 oz stainless steel carbine buffer, and a chrome silicon coated spring. The tube accepts SB Tactical Pistol Brace and standard carbine stocks, and the buffer weight suits 5.56 caliber cycling with most barrel lengths. The complete buffer assembly adds 9.6 oz to the build. All components are US-made and ship ready to install with the included proprietary barrel nut and mounting hardware.
