Centurion Arms C4 (Quad) Rail – Mid-Length Cutout Handguard – AR15/M4

Description

The Centurion patented C4 rail system is a lightweight, rugged, 2 piece free float rail that when installed gives the uppers a continuous 12 O’clock rail. The C4 system is the lightest and most rigid rail that clamps to a standard barrel nut on all AR15, M4, and M16 type weapons systems. This design allows the installation of the rail on an upper assembly without removing the front sight post or permanently attached muzzle devices. **Please note that some FSBs may need to be modified to fit by filing down the longer sling attachment ears so that they are not touching the handguard. Engraving is now machine engraved and black anodized….no white markings.**

This rail/handguard DOES NOT come with a standard barrel nut for installation. If one is needed, they can be purchased separately here.
