Seekins Precision’s Integrated Rail Mounting technology (iRMT) uppers integrate the rail mounting points into the upper retaining the stiffness of a true monolithic upper while allowing the rails to be completely modular. This new upper design is considerably thicker in the most critical area and will aid in squeezing all of the potential accuracy out of your rifle. Instead of a standard barrel nut our iRMT system uses an externally threaded, Titanium barrel nut with 1-1/8” wrench flats on it for simple installation. No special proprietary wrenches needed.
SP iRMT-R upper is compatible with Seekins Precision’s BAR rail and MCSR rails
