Steel 30mm Rings with 1 in. Inserts, Matte Black 660001

USTS Single Width Rings (Low Profile) ------------------------------------------- These 4140 steel rings were specifically designed for the heavy-hitting recoil of the .50 caliber BMG round in our double width configuration. Since our .50 caliber rings were a great success in taming the recoil, and securing zero under extreme conditions, we know there is also a need for quality rings that will work with the Magnum and other calibers as well. Some rings tend to lose the zero with the heavy hitting rounds On our single width rings, we found that the use of single nuts, together with four HOLOKROME cap screws on each ring is more than enough to affix the optic properly with ANY caliber including the Magnum loads. Designed with all the same features are our .50 caliber BMG rings, but lighter weight. US Systems Single Ring Set Features -------------------------------------------- This particular set of rings are 0.940" from the base to the centerline of your ring, and compatible with objective sizes up to 45mm. (Low Profile) They fit the standard MIL STD 1913 (Picatinny) rail and include a parkerized matte finish. The US Systems steel rings feature single 100% perfectly square cross-cut bolts, precision machined to snuggly fit the Picatinny rail cross-cut slots. This allows maximum contact with the MIL STD 1913 Picatinny cross-cut slot for a solid that will not move under extreme pressure or large caliber recoil. Each Ring Cap also features genuine HOLOKROME Hex Screws because only the best will do. For more versatility with several and optic configurations, we have also included perfectly matched pair of 1-inch inserts with every set of rings. The 1-inch inserts are “lipped” on both sides to eliminate movement. The USTS rings are the only Wire-EDM rings machined from one solid billet of 4140 chrome-molybdenum steel. The result is a highly accurate, super-strong steel ring set made to last a lifetime!
