The Porter Machine Works 4-Bolt Unimount is a one-piece scope mount made in Sydney. Each mount is CNC-machined from 7075-T651 aluminium plate and anodised locally, giving a rigid, light platform that holds zero on hard-recoiling hunting and precision rifles.

Choose your tube diameter, ring height and either a flat (0 MIL) base or 7 MIL (about 24 MOA) of built-in cant for extra elevation at long range.

30mm, 34mm and 36mm sizes are normally in stock. 35mm is made to order by Porter Machine Works, so allow extra time for it.
