Precisely CNC machined 6061-T6 aluminum medium-profile rings designed to fit standard Picatinny rails. The product is anodized in a matte black coating and fitted with a QD mount. 30mm diameter rings are placed on a 10mm high saddle and are compatible with optic tubes up to 50mm of objective outer diameter. Upper halves should be screwed with a force of 25 inch-lb/2.8nm. This setup ensures a firm grip on the optical sight and permanent zero retention. Lightweight, well-designed, and stable construction makes those mounting rings a perfect choice for mounting low-powered optics.
