The Trijicon Q-LOC 30mm Cantilever Scope Mount 1.535in (SKU AC22040) is a one-piece cantilever scope mount for 30 mm tubes, using Trijicon's Q-LOC quick-release lever system, with the optical axis 1.535 in (39 mm) above the rail.
How It Compares
Two things define a cantilever mount: height and elevation bias. This one sits at 1.535 in (39 mm) — the taller of the two heights Trijicon offers here, which suits an AR-pattern rifle where the scope has to clear the upper receiver and sit level with the shooter's eye — and it has no built-in elevation, so the scope's own turret travel is centred. If you want elevation built into the mount for long range, the same 1.535 in mount with 20 MOA and the lower 1.125 in mount with 20 MOA are the alternatives. Browse all rifle scope mounts or the full Trijicon optics range.
Ideal For
- AR-pattern rifles needing the scope forward and clear of the upper receiver
- Set-ups that come on and off the rail and must return to zero
- Shooters who want the factory Trijicon mount rather than an aftermarket copy
