Rail to optic center 1.060 (30mm & 1″), 1.125 & 1.250” (34mm) & 1.250 (35mm)
This mounting system is designed to handle large objectives up to 56mm (34mm Mount) and 50mm (30mm Mount).
This system provides over 3.5″ of rail interface providing extreme lockup on the host rifles scope base. Our NATO spec rail interface system pulls the mount onto the top of the pic rail, providing over 200% more rail contact than other competitive mounting systems that pinch the rail.
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 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.
