Catch Cant Before the Shot

A compact visual level reference for standard 21 mm Picatinny rails.

A rifle that looks level at a glance can still be slightly canted. The TacSight™ Anti-Cant Rail Level gives you a clear green bubble reference directly on your setup, helping you check rifle orientation before each shot without adding a bulky electronic device.

A Fast Visual Reference at the Rail

Keep the bubble between its reference lines to check cant while setting up your shooting position. The simple mechanical vial requires no batteries, app, or charging cable.

✔️ Visible Spirit Bubble
The bright green vial is easy to locate and read at a glance.

✔️ Standard 21 mm Picatinny Fit
Designed to fit a standard 21 mm Picatinny rail. Check available rail space and nearby accessory clearance before ordering.

✔️ Compact, Lightweight Profile
Approximately 21 g, so it adds a useful reference without a large electronic housing.

✔️ 6061-T6 Aluminum Body
Matte-black construction keeps the setup clean and consistent with common rifle accessories.

What It Does—and What It Does Not Do

The TacSight™ is a rail-mounted anti-cant reference. It mounts in an available compatible rail position so you can visually check the bubble. Your optic remains secured in its own rings or mount; the scope does not sit on top of this accessory.
