The Centurion Arms C4 M-LOK rail is a lightweight, rugged, 2-piece free float rail that offers a continuous 12 o'clock rail. The C4 allows for a rigid rail platform and features the M-LOK interface at 3 positions. The 2-piece design allows for installation to a standard barrel nut without removal of the muzzle device or front sight post.

The 12" Carbine FSP model will fit Carbine gas systems with an FSP and barrel long enough to clear the rail.

**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
