Benelli M4 Mounting Rail Screws

Rx Arms Custom Torx Benelli M4 Mounting Rail Screws, set of 5.  Replaces both the OEM Washer (Benelli 70077), and the OEM Screw (Benelli 70123) for a streamlined solution.  Instead of using a screw and serrated washer, we have optimized these screws with a nylon (Nylok) patch for vibration resistance, and a robust Torx T25 head.

The self-locking nylon (Nylok) patch is bonded onto the threads of each screw for vibration resistance. Since nylon has great memory characteristics, this locking element can be reused several times.   These screws are CNC machined from a heat treated 4142 CroMoly steel, finished in black oxide.

Engineered for use with the Benelli M4 OEM Pic Rail, and all Rx Arms Picatinny/Optic Mounts for the Benelli M4/M1014 receiver.  Made In Canada.

Installation Instructions:

1. Do not install with any washer
2. Use a Torx T25 Bit
3. We recommend 14-15 inlb torque for the Rx Arms Mounting Rail Screws.  Benelli spec is 16inlb, but we prefer to err on the side of caution.

NOTE: The Nylok Patch will provide resistance upon first use. This is completely normal.  Ensure initial 1-2 threads are properly threaded in the receiver before engaging the Nylok patch.
