Frequently Asked Questions
Will the Steiner T-Series Cantilever Mount fit my AR-15?
Yes. The Steiner T-Series Cantilever Mount is specifically designed for AR-15 and flattop rifle platforms equipped with a standard Picatinny (MIL-STD-1913) rail. The cantilever design shifts the optic forward to accommodate the extended eye relief typically required on direct-impingement and gas-piston AR-style rifles.
Why choose a 40mm height mount for my optic?
A 40mm mount height is well-suited for AR-platform shooters who use a riser or flat-top upper, as it aligns the centerline of the scope with a natural cheek weld on standard AR stocks. This height helps maintain a consistent and comfortable shooting position, which is critical for accuracy during rapid or extended shooting sessions.
Is this mount compatible with 30mm scope tubes as well?
No — the Steiner T-Series Cantilever Mount is specifically sized for 34mm scope tubes. Using it with a 30mm or 1-inch tube would not provide a secure fit and could damage both the mount and the optic. If you have a 30mm scope, you'll want to look for a mount designated for that tube diameter.
