34 mm Mounts for Picatinny/Weaver Rails
The 34 mm tube diameter is found on especially high-end, high-transmission riflescopes with a large internal windage/elevation adjustment range. For Picatinny and Weaver rails we carry mounts from Scalarworks and Sportsmatch UK.
Scalarworks FUSE/03 – Premium One-Piece Mount
The Scalarworks FUSE/03 (34 mm) is the natural evolution of the proven FUSE concept for the larger tube diameter: a high-end one-piece mount with a patented LevelDrive system for precise, repeatable alignment and a 1.57-inch height.
Sportsmatch UK: Classic Two-Piece
From Sportsmatch UK we carry both a high two-piece standard mount and a fully adjustable two-piece variant for 34 mm, suited to individual adjustment needs.

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.
