The Troy Industries MRF-CX is the strongest user installed free floating rail available. The MRF-CX is designed to install on a standard factory M4 barrel, the mounting system reinforces the factory barrel nut and the anti-rotational tabs keep everything tight. The top rail aligns with the upper receiver to form a continuous, uninterrupted rail with a cut-out for the front sight post. The MRF-CX rail will give you more room to mount foregrips, lights and accessories than the standard drop-in carbine rails and does not require specialized tools to disassemble the upper or upgraded gas blocks to gain the extra rail space. There are 4 attachment points for push button quick detach sling swivels, on both the left and right side. This rail is extremely light weight and only adds an additional 9 ounces over the standard two piece M4 handguard. Installation of this rail requires the removal of the delta ring, weld spring and snap ring; this can be done with a rotary tool or by completely disassembling the upper receiver.
