Centurion Arms 7.62 M-LOK CMR Rail Systems


The CMR (Centurion Modular Rail) is now available in M-LOK for 7.62 AR-10/SR-25 platforms.  The monolithic 6061-T6 Aluminum extrusion is incredibly robust and light weight.  With Centurion's slim profile, the 7.62 M-LOK CMR is incredibly light for full length rails.  With integrated, rotation limited QD sockets, full length 12 o'clock picatinny rail, and M-LOK slots at 3, 6, and 9 o'clock -- this rail system is paired down to just the essentials.  

The Centurion M-LOK CMR rails are compatible with M-LOK accessories.  M-LOK has been tested and found to be to be more resilient than Keymod mounting and by all indications is going to be the lightweight mounting system for firearms accessories.

Top Shelf , bomb proof 308 rail

Posted by Bill | (Posted on 4/27/2018)

The rail is very nice, very detailed. I really like the barrel nut/mounting interface. Once this is all locked down it is extremely rigid and feels bomb proof. Every detail of the piece is done nice right down to the inside profiles of the rail. The shape and size fits the hand perfect, its not even close to bulky like most 308 rails. The rail itself feels light but solid, the barrel nut is long and locks down nicely with the provided tool. The box came with an excellent instruction sheet, one page straight forward......its worth every penny but we all wish things were cheaper....however the craftsmanship gives me no remorse
