Frequently Asked Questions About 34 mm Picatinny/Weaver Mounts

What is a 34 mm tube used for?

34 mm is the largest common tube diameter and is found on high-end riflescopes that need to transmit especially large amounts of light and offer a large internal adjustment range.

Does a 34 mm mount also fit 30 mm scopes?

No, the tube diameter must exactly match your riflescope. For 30 mm tubes you'll find the matching mounts here.

How tight should I tighten the mount?

Recommended torque is usually around 2.0-2.2 Nm for the ring screws at the riflescope and around 3.4-5.6 Nm for fixing the mount to the rail, depending on the manufacturer. Overtightening can damage the scope tube.
