The A.R.M.S.® Selective Integrated Rail System The A.R.M.S.® Selective Integrated Rail System includes more unique and helpful features for the professional user than all other devices combined.

This modular receiver sleeving system is a hand guard universal mounting system that leaves the barrel totally free-floating while providing a rigid ultra-light platform on which to mount virtually any mission specific accessory.
