C4 MLOK 12in FSP (For Carbine Gas FSB's)

The MLOK C4 rail system is based off the patented quad rail version. It is a lightweight, rugged, 2-piece free float rail that when installed gives the uppers a continuous 12o clock rail and MLOK slots for the 3,6, and 9 o clock positions. 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.
 
Fits MIL-Spec uppers.  Many billet uppers will not accept the alignment tabs without modification.  
 
**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

    Favorite rail

    Bought for an lmt fsp upper, quick remove of the delta ring and the handguard cap up front and this installs on super easy. Rock solid as well. Rail contacted the sling loops on the fsp so I took it apart and filed that down too. So if you're fine modifying a pre built upper this will work for you, if you're looking for a drop in solution this isn't it. Rail is solid, will be using centurion rails from now on. Battle axe blem laser engraving is a cool touch too.
