AR-15 Grip Screw and Lock Washer Set

The Potomac Armory AR-15 Grip Screw and Star Lock Washer is a reliable solution for securing any AR-15, M16, or M4 grip to a lower receiver. Featuring a durable steel 1/4-28 thread pattern, it fits all standard grips and lower receivers. Precision-manufactured, this essential component ensures a secure fit every time.

Potomac Armory sources this part from a number of US domestic manufacturers, so you should consider this a generic part.  Normally, this will have a flat head screw and be a bright steel color, but also could be blackened steel and a hex head bolt, depending upon suppliers.

We list it here only as a convenience to customers who are purchasing a grip which does not include this hardware.
