Vortex 30mm Precision QR Extended Cantilever 2" Offset Mount CM-404

Mounting a 30mm scope on a flat-top AR-15 with a standard ring position often puts the scope too far back for comfortable eye relief — a problem that shows up the first time you get behind the rifle and have to crane your neck to find the sight picture. The Vortex 30mm Scope Mount CM-404 solves that problem directly with a 2-inch forward offset that puts your scope where it needs to be for natural, repeatable head placement on the AR platform, without compromising mounting security or zero retention.

The Vortex Cantilever Scope Mount CM-404 moves your scope 2 inches forward of where a standard ring mount would place it, giving you the eye relief and head position that AR-platform rifles demand for comfortable, consistent shooting. For AR-15 shooters who have dealt with the awkward reach that non-offset mounts create on flat-top builds, the 2-inch cantilever makes an immediate, noticeable difference in how naturally the rifle mounts and how consistently you find the same sight picture shot after shot.

The quick release scope mount mechanism allows fast, tool-free removal and reinstallation of the entire scope and mount assembly when the situation calls for it. The quick-release lever locks securely in the mounted position and holds your zero reliably through the recoil of hard AR use, then releases cleanly when you need to remove the optic without any tools or time-consuming disassembly.

The Vortex cantilever mount CM-404 is designed specifically for flat-top AR-15 rifles running 30mm scope tubes — the most common combination that benefits from a cantilever mounting solution. The Vortex scope mount fits standard Picatinny rails securely and holds your optic in the correct position for the AR shooting geometry.
