BKL 4" Long Unitized Dovetail Mount, 25.4 mm

• Unitized 4-inch clamping platform: The long one-piece design spreads recoil and handling forces across more rail surface, helping a 1-inch riflescope stay aligned on airguns and rimfire rifles that see frequent use.
• Six-screw dovetail clamp: A larger number of clamping screws increases grip on 11 mm and 3/8-inch dovetail rails, which is especially useful on harder-kicking magnum airguns and semi-auto rimfire actions.
• Patented auto-centering system: BKL’s self-aligning clamp design moves the clamping legs evenly as the screws are tightened, helping the mount seat more squarely on the rail and reducing setup frustration.
• 1-inch ring fit: Built for 25.4 mm (1 inch) scope tubes, this mount gives a straightforward solution for many classic hunting optics and rimfire scopes without needing reducers or extra adapters.
• Aircraft-grade aluminum construction: The aluminum build keeps weight manageable while still providing the rigidity needed for a stable optic mounting platform in field and range use.

About the BKL 1 Inch Mounts Series

BKL 1 Inch Mounts are the company’s 200 Series, built for 1-inch scope tubes and standard 3/8-inch rimfire or 11 mm airgun dovetail rails. The series is aimed at shooters who need a secure mounting solution for airguns and rimfire rifles without moving to a heavier centerfire-style base system. A defining feature across the range is BKL’s patented auto-centering clamping system, which moves both clamping legs equally as the screws are tightened so the mount stays centered on the rail.

The series also uses a practical clamp-spreading arrangement that allows the screws to be moved to separate holes to widen the clamp during installation. That makes these mounts easier to fit on tight dovetail rails while preserving a firm hold once installed. Within the family, BKL offers unitized mounts, cantilever designs, separate rings, offset versions, high models, and drop-compensated variants, so the line covers everything from compact rimfire scopes to setups that need extra clearance or elevation help. Built from aircraft-grade aluminum alloy, the series focuses on low weight, repeatable alignment, and compatibility with the dovetail-equipped rifles and airguns for which BKL is best known.

About the BKL 4" Long Unitized Dovetail Mount, 25.4 mm

The BKL 4" Long Unitized Dovetail Mount, 25.4 mm is a fixed one-piece mount made for shooters who want more clamping surface and a more rigid ring relationship than separate rings can provide. Its 4-inch overall and clamp length gives the mount a long footprint on the rail, which helps distribute stress more evenly and supports consistent scope positioning on airguns and rimfire rifles. For rifles that see repeated firing cycles or frequent transport, that added contact area can help the optic stay settled.

This model is built around 25.4 mm (1 inch) scope tubes and uses six dovetail clamp screws to secure the mount to the rail. In practical terms, that makes it a strong choice for magnum airguns and semi-auto rimfire actions, where a mount benefits from extra grip and resistance to movement. The unitized layout also keeps ring spacing fixed, which can simplify installation and maintain alignment across the scope tube.

BKL’s auto-centering clamping system is one of the mount’s most useful design features. As the screws are tightened, the clamping legs move evenly, helping the mount center itself on compatible dovetail rails. Combined with the aluminium construction, this gives the mount a balance of rigidity and moderate weight. With a 5.1 oz weight, 0.6" ring width, and 0.125" turret clearance, it suits practical rimfire and airgun setups where secure mounting matters more than added complexity.

About BKL Technologies

BKL Technologies originated in Brownsville, Texas, in 1998 and focuses on scope-mounting systems for airguns and rimfire rifles. In December 2008, Auto-Numatic Corp. acquired the company and moved operations to Fort Worth, Texas. BKL’s product range includes scope mounts, rings, dovetail adapters, risers, and scope levels, with a strong emphasis on the 11 mm and 3/8-inch dovetail platforms commonly found on rimfire rifles and airguns.

A key part of the brand’s identity is its patented auto-centering clamping system, designed to self-align as the mount is tightened. BKL also manufactures its mounts and adapters from aircraft-grade aluminum alloy, keeping the products light while maintaining the stiffness needed for dependable optic support. The company’s reputation is built on practical mounting solutions made in Texas for shooters using traditional dovetail-equipped rifles.
