Product Info for Bobro Engineering Trijicon MRO Riser

The Trijicon MRO Mount features the Patented US Patent 8,567,105 BLAC lever system which requires no manual adjustment to attain a proper, rock solid engagement on a 1913 Picatinny rail. The system is modular and can utilize offset risers as well as cantilevered risers. The riser features rear serrations to minimize glare. Like all BLAC mounts, the lever can be mounted any side or direction. When just using the low base, lever can only be used on the left side. The Trijicon MRO Mount comes with all tools necessary for installation.image
