IRMT-3 V3 Upper
Description

Description

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 AR15 rifle. Instead of a standard barrel nut our IRMT system uses an externally threaded, Steel barrel nut with 1-1/8” wrench flats on it for simple installation. No special proprietary wrenches needed.

The IRMT-3 V3 Upper is only compatible with the Seekins Precision SP3R V3 rail system.


Ships with a forward assist & dust door already installed.

Exceptional!

I'm not easily impressed. far from it. this upper however is very impressive. Excellent finish and high quality and attention to detail are evident throughout. paired with their sp3R v3 rail system the upper and rail feel like one, extremely solid, monolithic assembly. solid connection, excellent mounting, and perfect alignment.

I used this system for a 24" varmint rifle build and it's perfect. the flat bottom of the rail sits perfectly in my benchrest support, and it's obvious it would be very stable rested on any flat surface.

it's quality and innovation like this that have made me a huge Seekins Precision fan and a customer for life.
