The Steiner T-Series MSR 30mm Super High matte scope mount is a one-piece cantilever design purpose-built for AR-15 platforms and flat-top receivers. If you're running a modern tactical rifle and need a rock-solid way to mount a 30mm optic, this aluminum mount delivers the rigidity and lightweight performance that serious shooters demand. The cantilever architecture extends your scope mounting forward over the receiver, giving you the eye relief and sight picture control that matter in precision shooting, hunting, and tactical applications.

Machined from aircraft-grade aluminum alloy, the T-Series mount won't flex or shift zero under recoil or rough handling. Weighing just enough to be substantial without being a burden, it strikes the balance between durability and practicality that AR builders and shooters value. The matte finish resists glint and blends with mil-spec furniture, and the one-piece design means fewer components to maintain or worry about coming loose.

Installation is straightforward: the mount locks directly to your Picatinny rail with no secondary hardware needed. The 40mm height places your 30mm scope at an optimal sight line for most AR configurations, whether you're running irons co-witnessed below, going pure optic, or building a precision long-range setup. This is the kind of no-nonsense mount that works as hard as you do in the field, at the range, or on deployment.

Frequently Asked Questions

Will this mount fit my AR-15?

Yes. The Steiner T-Series MSR is designed specifically for AR-15 and flat-top platforms with Picatinny rails. It mounts directly to the receiver rail.

What scope tube diameter does this mount support?

This mount is designed for 30mm diameter scopes, which is the standard for modern tactical and hunting optics.

What height is this mount, and will it co-witness with irons?

The mount sits at 40mm height. This height works well for most AR setups; whether it will allow iron sights to be used underneath depends on your specific rail system and optic. Check your optic's eye relief and your intended sight configuration to confirm fit.

Is this a one-piece or two-piece mount?

This is a one-piece cantilever design, which means the entire assembly is unified and mounts as a single unit to the rail—no separate rings to adjust or secure.
