The Wilson Combat V3 Ultralight AR Scope Mount is the most dependable lightweight mounting solution for your AR. At a mere six ounces, it's ideal for tactical and hunting applications and its patented triple bolt construction can brave even the mightiest of calibers such as .338 Federal, .458 HAM'R or .50 Beowulf. Crafted from 7075 Aluminum with a sleek satin anodized finish, the V3 has a short 5.25" long frame and 1.5" height that is specifically built for tactical scopes up to 50mm objective lens capacity. Its semi-extended offset allows users to attain proper eye relief without having their scope exposed to potentially damaging tuning fork motions due to extended cantilever mounts. NOTE: We recommend 20 inch pounds to torque on ring screws and 30 inch pounds on cross bolt clamp screws.
