Overview

This quick-detach base is designed to let a shooter move a 3x magnifier out of the way when a closer sight picture is needed, then return it to position without changing setups. It clamps to a Picatinny-style rail and uses a low-profile design with an extended scope ring for a secure hold on the magnifier body. The mount can also be used with other 30mm optics, and additional bases allow the magnifier to be transferred between rifles. A separate co-witness spacer is available for use with factory-height backup iron sights.

Considerations & Trade-offs

  • This is the TwistMount base only; the magnifier and any extra bases are sold separately.
  • A Co-Witness Spacer is not included and must be purchased separately if a raised sight axis is needed for factory-height backup irons.
  • It is designed for Picatinny-style rails, so compatibility depends on the rail system in use.
  • The mount is specified for 30mm optics, so it is not a universal fit for optics outside that size.
