Warne USL1 Universal Scope Level 1" Tube Diameter Aluminum - Matte Black

The Warne USL1 Universal Scope Level is a compact, clamp-on bubble level engineered to give precision shooters a fast, at-a-glance confirmation that their riflescope reticle is perfectly plumb to the bore. Cant is one of the most common - and most easily corrected - causes of left/right misses at distance, and mounting a level directly to the scope body puts the reference exactly where the shooter's eye is already focused, no need to break position or look down at the receiver.

Designed to fit 1-inch scope tubes, the USL1 clamps securely around the main body of the scope and presents a clear vial on top of the optic. The unit is fully ambidextrous, so it works equally well for right- and left-handed shooters, and is the 1-inch variant of Warne's Universal Scope Level family, which is also offered in 30mm, 34mm, and 35mm versions to match nearly any modern riflescope.

The housing is machined from lightweight 6061 aluminum with a low-glare matte black anodized finish, keeping the level at just 0.9 oz so it adds virtually no weight to the optic. The low-profile, 1-piece design sits cleanly on the scope tube without interfering with turret caps, eyepiece focus, or sunshade operation, and installs quickly without altering your existing mount setup.

Designed and made in the USA by Warne, the USL1 is a simple, rugged add-on that makes dialing long-range hits more repeatable - whether you're behind a competition rifle, a hunting rig, or a tactical platform.
