Designed and Manufactured in the USA
Our mounts are proudly designed, manufactured, and sold right here in the USA. Each mount begins as a billet of 6061-T6 aluminum and is CNC machined in our Lincoln, Nebraska shop to exacting standards. After machining, we sandblast and finish every mount with H-Series Cerakote—a two part, heat cured ceramic coating that delivers superior scratch resistance while preserving dimensional accuracy. We take pride in supporting American manufacturing and source our raw materials from companies that share the same commitment.

Just installed on MK IV 22/45 Lite. Works perfectly and allowed the RMR to mount much closer to the bore. Fair price, quick delivery, excellent customer service. I used 1/8” mounting screws as the 3/16” bottomed out
