Steiner T Srs Cntlvr 34mm 40mm Hgt

The Steiner T-Series 34mm 40mm cantilever mount is a precision optics mounting solution engineered for AR-15 and flattop receiver platforms used in tactical, law enforcement, and military applications. This cantilevered design elevates your optic forward of the receiver, providing superior sight radius and enabling co-witness configurations with backup iron sights—a critical capability in dynamic operational environments where redundancy can save lives. Built for shooters who demand reliability under pressure, this mount bridges the gap between lightweight portability and absolute structural integrity.

Machined from aircraft-grade aluminum alloy, the Steiner T-Series cantilever mount weighs just 0.63 lbs while delivering the rigidity required to maintain zero under recoil and field conditions. The cantilever design shifts the optic's center mass forward, reducing felt recoil impulse and improving sight picture stability—factors that directly impact accuracy during extended engagement sequences. The 34mm tube diameter accommodates mid-range and precision optics, while the 40mm height provides optimal cheek weld positioning on most modern furniture configurations without requiring riser pads or additional spacers.

This mount is ideal for competitive shooters, patrol officers outfitting duty rifles, and military personnel building recce or designated marksman platforms. Its cantilever geometry works seamlessly with Picatinny-railed uppers and integrates with both magnified and unmagnified optics. Installation requires standard armorer-level tools and basic receiver rail familiarity; the robust aluminum construction resists corrosion and impact damage during transport and deployment. For shooters seeking a no-compromise mount that balances weight, strength, and ergonomic performance, the Steiner T-Series cantilever delivers proven field-tested reliability.
