The Centurion Arms CMR Rail is a lightweight, rugged, one piece free float handguard that uses a proprietary barrel nut and gives an AR upper a continuous 12 o'clock rail.
It was designed with the top 1913 rail for mounting the most common accessories, yet does away with the need for 1913 rail at the 3, 6, and 9 o'clock positions. Accessories can be directly mounted to it with a dedicated, simple, light-weight mount or a conventional 1913 rail section to be added and used if needed. Additionally, the CMR built in anti-rotation QD sling swivels in 4 positions.


  • Fully licensed by Centurion Arms
  • Precision CNC machined aluminum construction
  • Lightweight design
  • Matte black anodized finish
  • Modular 3, 6, and 9 o'clock sections allow you to add only the rail space/accessories needed
  • Steel thread inserts at specific holes to increase durability of threads
  • Integrated front and rear QD sling swivel points
  • Locking tabs prevent rail from rotating from prolonged use
  • Simple clamp design fixture directly onto proprietary barrel nut
  • Low profile gas block, barrel nut, and mock gas tube included

"All I can say about this rail that it's MEH. It's an nice looking rail fits nice on my Krytac but for some reason when I bought this rail the hex key holes looks deformed and was hared to screw in. I think PTS should of priced this rail a bit cheaper in my opinion

looks nice
Fits well

Hex key screws
Should of came with a rail segment would of given it a more stars

"This is actually a good quality rail. Fitment and finish are both very nice. The issue is the screw holes are 4mm metric. The accessory kit comes with 8-32 standard screws. Using the accessory kit screws will most likely cause you to strip the screw holes. You have two options:

A. Get the correct screws: M4-0.7 x 12 mm, black if you can find them

B. Re-thread the holes for 8-32nd.

"Probably one of the WORST handguards/rails I've ever bought. I held one of these on Spartan117GW's gun and I liked it. After that I ordered myself one with the accessories kit. Upon arrival I liked the weight, but I soon figured out that the accessory screws are made out of a soft metal and is an extremely tight fit.

-gas Block included

-poor screw hole
-poor accessory screws

Overall I would NEVER recommend this to anybody! For the price this should have Never happened.
