Sinclair International Linear Bubble Level

A linear bubble level from Sinclair International mounts along the rifle’s scope tube or rail to catch cant before it becomes a miss at distance. Even a couple of degrees of tilt can push a long-range shot off target, and a level like this gives you a quick visual check before the trigger break.

It’s a simple, inexpensive addition for anyone shooting at distance from a bench, tripod, or bipod, and a common accessory among precision rifle and long-range hunting shooters who need to trust their hold is truly vertical.
