For proper selection of the correct mount, see the data below to match the proper MPA BA Mount to your optic:

  • MPA BA 1.060″ Height – Erector Housing to main tube measurement of 0.145″ or shorter.
  • MPA BA 1.125″ Height – Erector Housing to main tube measurement of 0.210″ or shorter
  • MPA BA 1.250 Height – Erector Housing to main tube measurement of 0.330″ or shorter

Note: For US Optic Model ER-25, please select the 1.250″ height for your optic. This is due to the erector housing width and configuration and the necessary clearances required for proper fit. Also, please notify MPA if this is the optic you plan on using. A special top cap is required to clear the elevation turret cap.
