Questions & Answers
The ad says the ring height is “high” but what does that mean? How high above the standard 1.5” is it? Or is it just 1.5” at ring centerline?

I know this is an aged question, but I thought someone might benefit from an answer. I own three of these and the centerline height above rail is 1.5”.

Product Info for AT3 Tactical 30 mm Cantilever Scope Mount

High-Quality, Light Weight, and Recoil Resistantimage

Get your favorite 30mm optic mounted to your modern sporting rifle with the AT3 Tactical 30mm Cantilever Scope Mount. Designed to work perfectly with the new AT3 Red Tail Rifle Scope, you can easily install this mount on any Picatinny optic rail with a 30mm scope. It also features significant lightening cuts to massively reduce weight without compromising its durability.

Tough and Easy to Use

The AT3 Tactical 30mm Cantilever Scope Mount is machined from aircraft-grade aluminum and finished in anodized matte black for excellent wear resistance. This scope is designed to withstand the rigors of use while maintaining lightweight for long hauls in the field. The one-piece mount base features integral recoil stops to ensure your zero holds under recoil and lightening cuts to trim ounces before they become pounds.

This mount is taller than typical cantilever mounts, bringing your scope higher on center for fast target acquisition with Low Power Variable Optics. As a result, the extra height also prevents you from hunching awkwardly into your stock to get a good sight picture, especially shooting off-hand. The edges are also radiused to prevent snagging, scratching, or tearing of your gear.

We include everything you need for a simple installation the base, rings, screws, and a T20 Torx wrench is all it takes.

Note: We recommend tightening the screws for the top of the rings with a torque value of about 25 inch-lbs, and the side plate screw with a torque value of about 35 inch-lbs.
