The Sightmark Tactical 30mm/1" LQD Cantilever Mount is a quick-detach, single-piece base for 30mm riflescopes. This mount features a two-inch forward offset, allowing use of riflescopes requiring greater eye relief and providing a more comfortable cheek weld on AR-platform rifles. The 30mm LQD is constructed of durable aircraft-grade 6061-T6 aluminum and finished with a matte black, non-reflective coating. The LQD mount allows for quick and easy transfers from one firearm to another, on installing and removing from the same firearm while maintaining zero.

A cantilever mount moves the scope forward of its base. On this Sightmark mount the offset is two inches, which gives you longer eye relief and a more comfortable cheek weld on an AR-platform rifle, where the rail often sits too far back for a scope. It is one piece, 6061-T6 aluminum, for 30mm tubes.
It tilts the scope slightly nose-down, built into the base. That gives you about 20 MOA of extra elevation, roughly 21 inches at 100 yards, so you have more adjustment left for long shots. A 0 MOA mount sits flat and leaves all of that travel to the scope's own turret.
Most scopes can. The 20 MOA cant uses up some of your downward adjustment, so a scope with very little elevation travel may run out when you dial a 100-yard zero. Check your scope's total travel before you mount it. Torque the rings to 22 to 25 in-lbs with the included key.
