The X-Accu SCTM-57 34mm High Profile One-Piece Scope Mount is designed to securely mount compatible riflescopes with a 34mm main tube onto a 21mm Picatinny rail. Manufactured from 6061-T6 aluminium alloy, it features a full CNC-machined construction with a hard-anodised finish for durability.
The mount has a 40mm centre height, measured from the bottom of the mount to the centre of the scope rings, and a total length of 154mm. Each ring is secured with six screws, while the mounting base incorporates three cross bolts and anti-retreat features to help maintain a secure position on the rail.
Finished in matte black, this one-piece mount provides a stable mounting platform for compatible optics. It is specified to accommodate scopes with an objective lens diameter of up to 65mm, although actual clearance depends on the scope’s dimensions, rifle configuration and rail position.
