Seekins Precision IRMT Billet Upper

Seekins Precision IRMT Billet Upper

Availability: In stock




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. No special proprietary wrenches needed.

SP iRMT-R upper is compatible with Seekins Precision’s BAR rail and MCSR rails

Weight (as shipped) : 14.25 oz

Excellent Fit and Finish, Great EngineeringReview by
I purchased this Seekins Precision IRMT Billet Upper to use with a Seekins Precision Billet Lower and a MCSR handguard. The Upper and Lower fit together like a glove; there is not doubt that they have excellent CNC machining and engineering. If you want a great Upper and expect excellent fit and finish you will not be disappointed and if you add one of their MCSR handguards it will create one solid Upper. (Posted on 10/30/2016)

Great quality from Seekins. Machining is precise, with very tight fit between upper and hand guard. This is my second build with Seekins parts. There WILL be more Seekins builds in the safe! (Posted on 5/28/2016)
