Overview
Built for rifles equipped with a MIL-STD 1913 Picatinny receiver rail, these scope rings are intended for secure optic mounting in a serious field setup. Originally developed for the M40A3 Scout Sniper Rifle and the Unertl 10x scope, they are sold as matched pairs and serialized to help maintain precise alignment. The all-steel construction, hard black oxide finish, and Torx-head ring cap screws reflect a straightforward, duty-oriented design. Included inserts also allow use with 1" scope tubes, adding flexibility without changing the ring system.

Considerations & Trade-offs

- They are designed for MIL-STD 1913 Picatinny receiver rails, so compatibility depends on that rail standard.
- The 30mm format is the primary fit, but the included inserts are what allow use with 1" scope tubes.
- The hard black oxide finish and Torx-head cap screws are practical features, but they still require proper installation and torque discipline.
