Products Information Order Media

Below you'll find our most current stock number information. These days, most people prefer two-piece bases, so we've emphasized them below. For a bridge (one-piece) base, specify H, G, L, or C at the hyphen. For a satin stainless steel two-piece base (check for availability on our Specialty Rings & Bases page), add -SS after the stock number. Glossy Gunnur and Custum bases, as well as stainless steel bases, come with stainless steel cone screws. Fluted bases take additional post-production machining and may not always be immediately available. Classic Huntur bases (angular corners, sanding-belt finish) have been discontinued and are no longer stocked, but can still be ordered by special request. Just specify S1 or S2 instead of H1 or H2 at the end the Huntur stock numbers below.

NOTE: The last two characters of each stock number indicate grade (Huntur, Gunnur, Limited, Custum, or Fluted) and number of pieces. To order a satin stainless steel base, add -SS after the stock number. Not all bases are available in stainless steel. Ring-extending or short-ring-spacing bases are designed for certain scopes that may be too short for a standard Conetrol mount. The rear Conetrol ring typically sits just behind the shell ejection port, the front ring maybe an inch or so ahead of the port (between the two front screw holes for most screw-attached bases). If your scope would not allow this, you should order a ring-extending or short-ring-spacing base. Conetrol mounts are available for virtually any firearm made that will take a conventional top mount low over the receiver. If your gun is not listed among the popular models above, we might be able to identify a special combination of our two-piece bases that will work for you. Contact us with full particulars.

Solid rings require a scope with a straight tube on one end all the way to the end of the scope (no expanded lens bell). On such scopes, one solid ring may be used. NOTE: To order Conetrol rings in stainless steel, add -SS after the stock number. Only 1", 30mm, 34mm, and 35mm split rings are available in stainless steel. For 1", 26mm, and 26.5mm rings, the number preceding the letter in each stock number is the height of the ring in 64ths of an inch. The letter gives the grade, and the final number indicates the type: solid or split. For example, 8G3 is a one-inch Gunnur split ring (3 parts) that places the scope tube 8/64" (or 1/8") above the top of the base. For 30mm, 34mm, and 35mm rings, the first digit or digits (ignore the digit just before the letter) give the ring height in millimeters. For example, 70C3 is a 30mm Custum split ring that places the scope tube 7mm above the top of the base. Conetrol bases are normally 7/32" thick (5.6mm) above the highest part of the receiver. This distance plus ring height (1/16"-3/16" for our standard 1-inch rings, 3mm-7mm for our standard 30mm rings, etc.) is how high the mounted scope would sit above the highest part of the receiver. Thus, the bottom of a 1" scope tube would sit 9/32", 11/32" or 13/32" above the highest part of the receiver with low, medium, or high 1" rings, respectively. The bottom of a 30mm scope tube would sit 8.6mm, 10.6mm, or 12.6mm above the highest part of the receiver. Conetrol mounts have traditionally been very low and were often unable to accomodate scopes with very large objectives. For this reason, we've recently introduced Extra-High 1" and 30mm rings. Extra-High 1" rings (1/2" high) would place the bottom of a 1" scope tube 23/32" above the highest part of the receiver. Extra-High 30mm rings (13mm high) would place the bottom of a 30mm scope tube 18.6mm above the highest part of the receiver. HELPFUL HINT: Drill bits of different diameters can help you estimate the minimum mounting height required for a scope. Lay a drill bit on receiver and the scope on top of that, keeping everything aligned with the boreline of the barrel. The smallest drill bit that will get your scope high enough will tell you how high your mount needs to be. Base height plus ring height should be at least this distance. If you have time, you might want to order the base first before you order the rings.
