What is a 30mm scope mount used for?

A 30mm scope mount is used to securely attach a 30mm optic tube to an AR-15 or AR-10 rifle. These mounts ensure proper alignment, eye relief, and repeatable zero under recoil.

Should I use a cantilever mount on my AR-15?

Yes, cantilever mounts are ideal for AR-15 rifles because they extend the optic forward, allowing better eye relief and use of backup sights or accessories.

Are 30mm scope mounts compatible with Picatinny rails?

Most 30mm scope mounts are designed to fit Picatinny rails, which are standard on AR-15 and AR-10 platforms. Always check compatibility before purchase.

What is the benefit of a 20 MOA scope mount?

A 20 MOA mount provides a downward cant that allows for more elevation adjustment in your scope, which is especially useful for long-range shooting.
