AR-15 Pistol Grip Screw

Features

1. Mil-Spec Part Number — Built to the AN501D416 military specification used on standard A1/A2 AR-15 and M16 pistol grips.
2. 1/4-28 UNF Thread — Standard quarter-inch fine thread mates directly with the threaded boss on any mil-spec AR-15/M4 lower receiver.
3. 1-Inch Length — Correct length for use with standard A2 pistol grips and most aftermarket polymer grips without bottoming out or protruding.
4. Allen Head Drive — Internal hex socket installs and removes cleanly with a 3/16" Allen wrench — no risk of camming out a slotted head.
5. Black Phosphate Finish — Manganese phosphate coating resists corrosion and matches the parkerized finish of mil-spec lower receivers and small parts.
6. Hardened Steel Construction — Heat-treated steel body handles repeated torque without stripping threads or rounding the socket.
7. Drop-In Replacement — Direct factory replacement for lost, damaged, or stripped grip screws on AR-15, M4, and M16 platforms.
8. Pairs With Standard Lock Washer — Designed to be used with a 1/4" split lock washer (sold separately) to keep the grip seated under recoil.
