Description

Centurion Arms LLC is happy to announce the C4 MLOK® rail.

C4 MLOK MID CUT

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 oâclock 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.

Great FSP USGI option

Rail was very easy to install on my DD CHF 14.5 middy. Very light yet rigid option for my FSP gun that has a USGI nut. Completely modernized gun with ability to mount light, lasers, and sling.

Top notch!

Very nice rail. Installation is very simple as long as you have the basic tools to remove the delta ring. Also utilizes a standard barrel nut.

Centurion Arms C4 M-LOK Handguard - Midlength Cutout

Centurion Arms makes outstanding products, the fit and finish is second to none. I have 3 of their rails and this is my first fsb cutout model, it hugs the barrel and fsb, easy to install and allows for the mounting of m-lok accessories to adapt my build to my needs. I can't say enough good things about Centurion and AR15 Discounts!

Light, sturdy, and beautiful.

Using this handguard with my new 13.7 middy build with a JP adjustable FSB gas block. After some modifications to the FSB, I am happy to report that the handguard sits perfectly aligned as well as functioning 100% as it should be. It is light, rock solid, and super easy to install. A must for anyone wanting to build a FSB middy.

Great rail

Easy install. Rock solid. Great rail if you want to keep your front sight post.
