Frequently Asked Questions
Will this mount work on a standard AR-15 flat-top receiver?
Yes. The Steiner T-Series Cantilever Mount is specifically engineered for AR-15 and flat-top rifle platforms. It attaches directly to any standard Picatinny (MIL-STD-1913) rail, making it compatible with the vast majority of modern AR-style rifles right out of the box. No additional adapters are required.
Why choose a cantilever mount over a standard two-piece ring set?
A cantilever mount shifts the optic forward along the rail, which is essential on AR-15 platforms where the flat-top receiver alone often doesn't provide enough forward position for proper eye relief. The one-piece construction also eliminates the alignment hassles associated with two-piece ring sets, ensuring your scope stays true after repeated recoil and field use.
Is the 40mm height suitable for use with a standard AR-15 cheek weld?
Absolutely. The 40mm mount height is specifically chosen to align your eye naturally with a 30mm optic when using a standard AR-15 stock and cheek weld position. This height helps eliminate the need for a raised cheek piece on most collapsible and fixed stocks, providing a comfortable and consistent shooting experience across a wide range of shooters.
