C4 Rail (7in - 12in)
$230.00
Description
The Centurion patented C4 rail system is a lightweight, rugged, 2 piece free float rail that when installed gives the uppers a continuous 12o'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
**Please Note: Current version of the rail has some slight cosmetic differences from stock photos
Engraving is now machine engraved and black anodized....no white markings.

The rail was easy to install and is rock solid. I've had a chance to use this rail for a few months now and I absolutely love it.
Top shelf quality rail. Precisely machined with excellent anodizing, lightweight and handy yet robust. Centurion Arms products have no peer.
Great rail , a little expensive but Centurion Arms makes great items. If you want solid equipment , from a solid company this is it. Veteran owned and operated means a lot. Will continue to buy from them.
Most Rock Solid Font Sight Post Cutout Rail that I have used and it uses a standard barrel nut. No need for proprietary tools. Outstanding!
If your tool collection is a Dremel, some hex wrenches, and some oil you have everything you need for installing this rail.
I use this so I can access an adjustable gas block and have an extended sight radius. It's lightweight enough that you can carry it at a class all day long and sturdy enough that when it gets smashed into a door frame at that class it won't bend.
