The Centurion Arms C4 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 Picatinny interface at 4 positions. The 2-piece design allows for installation to a standard barrel nut without removal of the muzzle device or front sight post.
The Carbine Cutout model will fit Carbine gas systems with an FSP.
**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
