Rx Arms Solutions Benelli M4 Picatinny Rail Mil Spec. Made from 6061-T6 Aluminum with Type III Hard Coat Annodize black.. The original picatinny rail on the Benelli M4 is not true Mil Spec due to the cutout down the middle of the rail, which can cause problems and potential damage with optics mounts.

In addition, it provides compatibility with the Rx Arms Solutions Benelli M4 Handguard Compatible M-LOK® Heat Shield via the boss hole at the front of the picatinny rail. Made In Canada.

Didn’t fit my turkenelli, as the receiver holes were different, seemed fine though won’t let me review only the other items so 4 stars quality seems ok but didn’t come with screws so minus a star

Rx arms picatinny rail should fit the heat shield a little more snug
Robb Hutzal (store manager) –
Hey Kevin, a small piece of thin tape on the top of the boss can snug the heat shield down more if desired.

Works as advertised, essential to mount the heat shield MLOK rail. Easy install, instructions clear. Do as the man says and torque it properly.

It’s a pic rail, not much to say.
John Blanck (verified owner) –
This Pic rail section was needed to mount my Holosun 510 and interface with the RX Arms Heat Shield. The installation was Simple, using the original mounting hardware my Benelli came with. As well, the RX Arms bolt release tab is a Must Have as it makes that bolt release so much easier than stock.
