EGW advises verifying the hole spacing on your receiver to ensure compatibility with their published dimensions. The picatinny cross slots extend the entire length of the rail, providing shooters with flexibility in mounting scope rings and other accessories. The central channel reduces the overall weight of the mount and, in many instances, does not interfere with the use of factory iron sights. Their one-piece scope mounts are an ideal choice for both hunters and tactical shooters. These mounts are precision-machined in-house using advanced machining centers. Post-machining, the mounts undergo tumbling, sandblasting and type II anodizing to ensure long-lasting durability. For installation, EGW recommends applying 20 in-lb of torque and a drop of blue Loctite (sold separately). They suggest using a 0 MOA mount for shooting distances of 0 yd - 150 yd and a 20 MOA mount for distances of 150 yd - 300 yd. When zeroing a rifle with a 20 MOA mount, it is recommended to zero at 200 yd. All components of the mount, including mounting screws, wrench and packaging, are manufactured in the USA.
