* Required Fields





The MCSR rail is a comfortable, extremely light weight modular rail system that will work in any situation as well as comfortably fit a suppressor inside the rail. MCSR V2 rail is designed so that the 3,6, and 9 o'clock positions will now accept all keymod accessories and have two anti-rotation QD points per side (6 total). The internal dimension of the MCSR V2 has increased to 1.8" to accommodate most suppressors on the market. The top picatinny rail is now a solid integrated to the new MCSR V2 rail as the original MCSR rail has been discontinued and is no longer being produced. With the addition of the keymod cuts on the sides of the MCSR V2 rail, we will no longer be shipping the Seekins Precision Proprietary picatinny side sections with the new rail.

I ordered this rail in 7" length for a 300BLK 6.5" barrel by V Seven. It fit perfect, however, I did receive a bad barrel nut which Seekins was VERY apologetic for (They have an unlimited lifetime warranty - IT TRUE.) and no questions asked sent me a new one. They changed their design due to torque being applied inappropriately by the "riflesmith" a.k.a. every man/woman that builds an AR in their garage. Rainier just had an older barrel nut, rail is still the same. They even sent extra set screws and allen keys which was unnecessary but appreciated. Customer service is a 110% in my books and their rail looks great and feels great. My 1.5" OD solvent tube fit under it perfectly for the record. (Posted on 12/14/2016)
