Centurion Arms AR-15 C4 M-LOK Rail

Centurion Arms is happy to announce, and we've eagerly awaited, the C4 M-LOK rail!

The C4 M-LOK rail is based on Centurion's patented quad rail design.  This venerable design is awesome for several reasons.  The C4 is a lightweight, rugged, 2-piece design, it clamps to the OEM AR-15 barrel nut.  It can be assembled/disassembled without removing the front sight post or pinned muzzle devices.  Also, it is a strong design -- the C4 was the direct competitor to the Daniel Defense RIS rails and it was lighter, less expensive, and just as robust.  TheC4 M-LOK is bringing this design into the modern age.
