NEW!! Centurion Arms 5.56 CMR Rail System!!!
Our patent-pending CMR rail system is a lightweight, rugged, one
piece, free float hand guard that, when installed, gives the upper a
continuous 12 o’clock rail. The CMR system clamps to a proprietary
barrel nut that can be installed on all AR15, M4, and M16 type weapons systems.
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. Here, other accessories can be directly mounted to
it with a dedicated, simple, light-weight, mount. However, it does allow
for 1913 rail to be added, if needed, for some less common accessories.
Additionally, we built in anti-rotation QD sling swivels in 4
The main objective was to have a smaller, lighter weight, more
ergonomic, hand guard that maintains or enhances functionality for the
end user. As professional end users ourselves, we know the importance
of keeping things simple and that was our design intent here... a
K.I.S.S. (keep it simple, stupid) system.
