Centurion Arms has introduced a new rail for 7.62 guns. It is a round modular fire arm that incorporates a full length Picatinny rail along the top. It utilizes a proprietary nut to attach, leaving a free float barrel. In addition to positions that accept rail sections where you want them, the rail also features QD sling attachment points at the barrel and receiver ends of the fore end. This first run is for the DPMS system but look for Stoner- style system compatability soon. Also a slightly scaled down version for the 5.56 is in the works.
Centurion also offers their own attachment for the SureFire Scout Light. It is reversible and mounts directly to the rail. In fact, you don’t require a Picatinny rail section to attach most accessories. And they are working toward eliminating redundant, unneeded 1913 rail segments wherever possible.
