The Milspin Optic Mount Adapter plate is a premium accessory for your firearm that is designed, engineered, and manufactured 100% in the USA by veterans. Unlike cheap competitor parts that come from overseas, made by companies in countries where owning firearms is not even allowed, the Milspin adapter plate is built to the highest standards of quality and precision. Precision machined from a solid block of 6061 Aircraft Grade Aluminum, this mount is designed specifically to prevent unwanted movement in all directions of both the adapter plate and optic under the high stresses encountered when cycling rounds. Unlike competitor parts, which are inadequately designed to accommodate these stresses, this mount is built to last and will not end up with loose or sheared screws that significantly impact the accuracy of your optic. The Milspin Optic Mount is professionally anodized matching factory finish. This provides an ultra-durable, long-lasting finish that will withstand the harshest conditions you may encounter in the field or on the range.
