Talley 1ACI Anti-Cant Indicator for 1" Tubes - Aluminum, Black Anodized Finish

The Talley 1ACI Anti-Cant Indicator for 1" scope tubes is a simple, effective tool for ensuring your rifle scope sits perfectly level on your rifle. Cant—the unintended tilt of your scope's reticle relative to the vertical—degrades accuracy and can throw off your point of impact, especially at distance. This aluminum indicator mounts to your 1-inch scope tube and gives you a quick visual reference to check that your scope is plumb before you head to the range or field. If you're serious about consistent, repeatable accuracy, an anti-cant indicator is one of the easiest accuracy aids you can install.

The Talley 1ACI features a black anodized aluminum construction, built to withstand field use while staying light and unobtrusive on your rig. Installation is straightforward—it attaches to your 1-inch tube scope and requires no gunsmithing. Whether you're dialing in a new long-range hunting rifle, setting up a precision rimfire, or making sure your optic stays true after transport, this indicator removes guesswork from the leveling process.

Talley Manufacturing has a reputation for precision rifle accessories, and this indicator reflects that attention to detail. It's a no-frills, proven design that does exactly what it claims: help you catch and correct scope cant before it costs you accuracy at distance.

Frequently Asked Questions

Will this anti-cant indicator work with my 30mm scope?

No, the Talley 1ACI is designed specifically for 1-inch diameter scope tubes. If your scope has a 30mm tube, you'll need a different model.

Do I need any special tools to install it?

No. The 1ACI attaches directly to your 1-inch scope tube without additional tools or gunsmithing.

How does an anti-cant indicator improve accuracy?

When your scope is canted (tilted), the reticle is no longer truly vertical or horizontal with the rifle's action. This causes the bullet to impact off your intended point, especially at longer distances. The anti-cant indicator lets you see and correct that tilt before shooting.
