Considerations & Trade-offs

  • The 3" offset is designed for AR-style setups, so it may not suit rifles that need a more traditional scope position.
  • This mount is specified for 30mm scopes; it is not a universal fit for other tube diameters.
  • The listed center height of 1.59" and forward placement are fixed design choices, so they may not match every optic or shooting position.
  • At 7 oz for the 1" version and 6.75 oz for the 30mm version, it adds some weight to the rifle setup.
