Steiner T-Series MSR 34mm Matte Mount, Super High 25 MOA Adjustment

The Steiner T-Series MSR 34mm matte mount is a cantilever scope mount built for AR-15 and flattop receiver platforms. If you're running a modern tactical rifle, precision carbine, or competition AR and need to mount a 34mm tube optic with plenty of elevation adjustment, this single-piece aluminum design handles the job without fuss. The super high mounting height (40mm) and 25 MOA of upward adjustment let you dial in zero at distance or compensate for extreme bullet-drop scenarios, making it a solid choice for long-range shooters pushing their AR platforms to the limit.

The mount is machined from aluminum alloy, keeping weight minimal while maintaining the rigidity required for optics that see real use. Picatinny attachment means it locks into any standard AR-15 receiver rail, and the cantilever design positions your 34mm scope far enough forward to clear most AR upper receivers and charging handles. The matte finish resists glare and plays well with modern gun aesthetics.

Whether you're setting up a precision rifle for distance shooting, a duty rifle build, or a long-range hunting carbine, a cantilever mount with this much elevation adjustment gives you flexibility to zero at different ranges or handle calibers with demanding ballistics. It's the kind of no-nonsense accessory that does exactly what it promises.
