Advanced Technology AR-15 Pistol Grip Screw and Star Lock Washer

The Advanced Technology AR-15 Pistol Grip Screw and Star Lock Washer is a compact hardware kit purpose-built for AR-15 and AR-10 lower receivers. This two-piece set pairs a steel 1/4-28 x 1" hex head bolt with a matching steel star lock washer, giving builders and gunsmiths a clean, secure way to mount a pistol grip without fighting the easily-stripped factory flat-head screw.

Cut from steel and finished in a low-glare matte black, this grip hardware is an ideal drop-in for new builds, grip swaps, or replacing a lost or damaged factory screw. The star lock washer bites into the receiver surface to keep the grip bolt from backing out under repeated recoil, so the grip stays locked down tight during live fire.

Whether you are assembling a complete lower from a parts kit or simply refreshing the hardware on an existing rifle, this Advanced Technology grip screw and washer set delivers a straightforward, inexpensive upgrade over the factory screw and lock washer.
