BKL 304 Silver 30mm 9-11mm Double Strap Rimfire Airgun Rifle Scope Mount Rings Top quality, super strong Double Strap, made in the USA mount rings for airgun and rimfire rifles. In stainless silver colour finish Medium/High profile 2 piece mount rings for 30mm tube scopes for fitting on 3/8" and 11mm airgun and rimfire dovetail base rails. Height - 0.680" - 17mm base to bottom of ring this equates to fitting scopes with a maximum lens case outer diameter measurement of 63mm. That is OUTER diameter and NOT lens size. See Clearance Guide below to learn how to assess if they are the right height for you and if so how much clearance you will have over the base Tube diameter: 30mm Fits: 3/8" and 11mm dovetail grooves Overall Length: 1" - 25mm Clamp Length: 1" - 25mm Ring Width: 1" - 25mm Bottom of Mount to bottom of Scope Tube: 0.68" - 17mm (32mm base to ring centre) Weight: 3.0 oz - 84g Finish: Matte Black This item sold as a set of 2 mounts Manufactured from aircraft grade aluminium on state of the art CNC machinery in Texas, USA Calculating scope to rifle body clearance The way you calculate the clearance is by halving the overall OUTSIDE diameter of your rifle scopes objective lens and then deducting half the rifle scopes body tube diameter. For scopes with a 30mm diameter body tube this means deducting 15mm. Note we say OUTSIDE diameter - this means NOT the lens diameter, you need to measure the whole outer casing diameter. The result gives you the minimum "saddle" dimension required - the measure from base of mount to bottom of the ring. The amount the saddle dimension is greater than the figure you have calculated is the amount of clearance your scopes objective will be clear of your rifles body. The saddle on these mounts is 17mm Worked Example - A scope is measured and found to have an outer case measurement of 57mm 57 divided by 2 = 28.5. 30mm scope so deduct 15mm = 13.5mm So the mount must have a saddle measure (base of mount to bottom of the ring) greater than 13.5mm or else it will ground out on the rifle body. These mounts have a 17mm saddle sow e can say there will be 3.5mm clearance (17 - 13.5 = 3.5) which makes for a very good fit. Calculating your rifle scopes clearance in this way does assume your dovetail or base is not raised above or below your rifles barrel. Note some rifles with high or adjustable cheek pieces may require higher scope mounts or risers so that your eye is in line with the rifle scope and your head is kept in an upright comfortable position. More on BKL Manufactured from aircraft grade aluminium on state of the art CNC machinery in Texas, USA What are the advantages of BKL mounting systems? 1 - Installation is performed easily because there are few components to contend with. BKL uses the same #8-32 screws for both scope ring and base clamps. One 9/64 hex wrench tightens all. 2 - The inside diameter where the rings clamp together is radiused to prevent scope damage. 3 - BKLs clamping system self aligns as it tightens down on 3/8” and 11mm dovetails. 4 - No lapping required. Do I have to center BKL scope mounts? No. All of our products center up as the pressure from the clamping system pulls down as it clamps in. About BKL - Made in Texas, USA BKL Technologies, manufacturer of the largest selection of airgun and rimfire scope mounts in the U.S. Our competition-grade scope mounting system includes scope mounts, scope rings, dovetail to weaver adapters, and scope risers that utilize a quick-installing and self-aligning clamping system that fits both 11mm and 3/8" dovetails. BKL mounts are compatible with popular rimfire manufacturers such as Anschutz, CZ, Feinwerkbau, Marlin, Remington, Savage, Suhl and air rifle manufacturers such as Air Arms, AirForce, Beeman, Benjamin, BSA, Crosman, Daystate, Diana, Gamo and Webley.
