One-piece scope mounts are simply THE BEST WAY to mount a riflescope to your firearm. (Scroll down for more photos.)

Only one-piece mounts can achieve perfect straightness and concentricity (without lapping). This insures a solid, accurate base for your scope that will never scratch it or warp the tube. F3R Machine produces high quality one-piece precision CNC-machined rifle scope mounts intended for hunters, benchrest shooters, long-range, extreme-long-range, Precision Rifle Series, and general target shooting. These are precision-machined, high-quality, ultra-rugged and reliable mono-block 6061 aluminum, machined and manufactured in Wisconsin, U.S.A. The scope tube bore tolerance is held under 0.0003″ for the pre-anodized 6061 aluminum. Additionally, we offer accessory rails to mount to the top of the scope mounts. We have over 2,000 satisfied customers, and many repeat-purchase customers.

F3R Machine scope mount nomenclature: “30MM-1.25H-STD” means “30 mm tube size, 1.25″ height, standard (non-cantilever).” Current models:
