What scopes use 34mm mounts?

34mm mounts are used with high-end tactical or long-range scopes that have a 34mm tube diameter, such as those from Nightforce, Vortex Razor, and similar optics.

Are 34mm mounts compatible with AR-15 rifles?

Yes, most 34mm mounts are designed to fit Picatinny rails on AR-15 and AR-10 platforms, offering solid attachment and repeatable zero.

Should I choose a cantilever or standard mount?

Cantilever mounts are ideal for AR-style rifles as they move the optic forward, helping with eye relief and positioning. Standard mounts work well if space and eye relief are already optimal.

What is a QD (quick detach) mount?

A QD mount allows you to remove or reinstall your scope without tools while maintaining zero. This is useful for switching between optics or for storage and transport.
