LBE Unlimited ARGRPSW AR-15 Pistol Grip Screw & Lock Washer Kit

The LBE Unlimited ARGRPSW provides a complete hardware solution for securing AR-15 pistol grips with professional-grade components. This precision-engineered screw and lock tooth washer combination eliminates grip loosening issues that plague standard installations.

What Makes This Different

Unlike basic grip screws that rely on thread friction alone, the ARGRPSW incorporates a lock tooth washer that bites into both the grip and receiver surfaces. This dual-engagement system prevents rotational movement under heavy use and recoil stress. The hardened steel construction exceeds mil-spec requirements for tensile strength and corrosion resistance.

Key Features

• Lock tooth washer prevents grip loosening during extended firing sessions
• Grade 8 steel construction with black oxide finish for corrosion protection
• Standard 1/4-28 thread pitch fits all mil-spec AR-15 lower receivers
• Precision machined threads ensure proper torque specification compliance
• Compatible with polymer, aluminum, and composite pistol grips
• Includes both screw and washer for complete installation
• Meets or exceeds military specification requirements

Field testing demonstrates superior retention compared to standard grip screws, maintaining proper torque through thousands of rounds. The lock washer design distributes clamping force evenly, preventing stress concentrations that can crack polymer grips. Law enforcement armorers and competitive shooters rely on this hardware for mission-critical applications where grip security cannot be compromised.
