1/4-28 X 1''lg. Ar15 Pistol Grip Screw

The 1/4-28 X 1'' AR15 Pistol Grip Screw by CMMG is a precision-engineered fastener purpose-built for AR-15 platform pistol grip assembly and retention. This component serves as a critical interface between the lower receiver and pistol grip, ensuring secure mechanical connection under the stress of firing cycles, recoil impulse, and tactical manipulation. Whether you're building a rifle for duty use, competition, or personal defense, a properly secured grip screw is non-negotiable for reliability and shooter control.

Manufactured to CMMG's exacting standards, this 1/4-28 threaded screw measures 1 inch in length and is engineered to provide consistent clamping force without over-torque failure or stripping. The 1/4-28 thread specification is the industry-standard configuration for AR-15 lower receivers, ensuring compatibility across OEM and aftermarket platforms. Proper installation—typically torqued to 15–20 inch-pounds—prevents grip rotation during fire and maintains the ergonomic geometry of your weapon system. CMMG's commitment to precision manufacturing means zero tolerance for dimensional drift, critical for maintaining zero and control.

Law enforcement, military, and competitive shooters rely on CMMG fasteners to maintain weapon integrity during extended operations and high-round-count training cycles. This screw is essential when replacing worn or damaged grip hardware, building a complete lower receiver, or ensuring your AR-15 meets armorer-level specifications. Installation is straightforward: insert through the grip's rear relief hole and thread into the lower receiver until snug, then apply final torque with a properly-calibrated driver. Stock a spare for field maintenance and emergency repairs.
