The newest version of our Benelli M4 Shotgun Rail Systems includes features from the Mod 2 and Mod 3 rails. We took a mil standard M1913 rail and reduced the non-channeled top rail by 0.1" to make our Low Profile top rail. By doing this, the front site post is fully visible; therefore, a channel is not needed down the center of the top rail. We also created a mil standard height top rail with a 6mm channel down the center so the front site post is not obscured. Any M1913 device will fit on either the low profile top rail or the standard height top rail.
Like the Mod 2 rail system, the new rail has integrated forward rails; however, the overall width of the forward rails has been reduced by nearly 1/4" over the Mod 2 design. This permits the rails to sit in tighter in relation to the fore end. We are offering two options for the forward rails: extended length and mid length. The extended length rail provides approximately 6" of side rail with 14 recoil stops. The mid length side rail provides 4" of rail, positioned forward. This allows for more access to the grip while offering 9 recoils stops, ample space to mount any desired weapon light. Taking from the Mod 3 rails, the proprietary attachment point on the receiver end of the rail allows for a quick detach shell holder to be mounted. The quick detach shell holder allows quick access to the trigger takedown pin as well as the ability to quickly change load requirements.

Return Policy for Rail Systems:
Rail systems may be returned within 30 days for a refund (minus shipping). The rails must be in original condition in order to be returned, meaning they must not have been mounted to the weapon or show any signs of wear. If there is evidence of wear on the rails, Sidearmor will return the rail (and components) to the customer, and no refund will be issued.
