OTIS Technology’s MSRS Rail System At A Glance


OTIS Technology has recently started shipping its new MSRS 2-piece rail system. The company designed it with the military customer in mind, so it provides strict adherence to the Mil-Spec standard, as an expedient and cost effective means for the military to upgrade the existing M4 inventory. The MSRS is a carbine length system that attaches to the weapon’s existing barrel nut thus eliminating the need for non-standard barrel nuts or barrel removal for installation.
