BKL 4" Long Unitized Dovetail Mount, 30 mm

• Unitized 4" mount body: The one-piece design keeps both rings aligned on the same base, which helps maintain a consistent scope position and reduces the chance of ring misalignment during installation.
• Six clamp screws over a 4" clamp length: The long clamping surface spreads recoil and vibration forces across more of the dovetail, giving a more secure hold on airguns and rimfire rifles that see frequent use.
• 30 mm ring fit: Built for 30 mm scope tubes, this mount suits larger optics commonly chosen for target shooting and hunting setups where added adjustment range or larger erector assemblies are common.
• Auto-Centering clamping system: BKL’s self-centering design moves the clamping legs equally as the mount is tightened, helping the mount sit centered on 3/8-inch and 11 mm dovetail rails without side bias.
• Aircraft-grade aluminum construction: The aluminum body keeps weight manageable while still providing the rigidity needed for repeatable scope mounting on dedicated airgun and rimfire platforms.

About the BKL 30 mm Mounts Series

BKL 30 mm Mounts are built around the company’s approach to 30 mm scope mounting on 3/8-inch and 11 mm dovetail rails. In BKL’s lineup, this family serves shooters who need a direct-to-dovetail solution for airguns, rimfire rifles, and target-oriented setups without moving to a separate rail interface. A defining feature of the series is BKL’s Auto-Centering clamping system, which moves both clamping legs equally as the mount is tightened so the assembly stays centered on the rail.

The series also reflects a practical mechanical design. BKL includes spreader holes to help open the clamp for installation on wider rails, and the range covers several configurations including independent rings, offset rings, unitized mounts, and adjustable mounts. Manufactured in Texas from aircraft-grade aluminum alloy, the series focuses on secure clamping, low added weight, and compatibility with the dovetail-equipped rifles and airguns that still dominate many training, hunting, and competition applications.

About the BKL 4" Long Unitized Dovetail Mount, 30 mm

The BKL 4" Long Unitized Dovetail Mount, 30 mm is a fixed mount made for shooters who want a longer, more stable mounting footprint on a dovetail-equipped rifle or airgun. Its 4" overall and clamp length gives the mount more contact area on the rail than compact ring sets, which is especially useful on spring-piston airguns, rimfire rifles, and other platforms where maintaining a secure hold matters over long shooting sessions. The unitized one-piece layout also helps keep both rings in line, simplifying scope installation and reducing the chance of stress from uneven ring positioning.

This model is configured for 30 mm scope tubes and uses six dovetail clamp screws to distribute clamping force across the full length of the base. In practice, that gives the mount a planted feel on 3/8-inch and 11 mm dovetails and makes it well suited to larger optics that benefit from a more substantial support structure. Because it uses BKL’s Auto-Centering system, the mount is designed to self-align on the rail as it is tightened, which can help achieve a cleaner, more centered installation.

With 0 MOA inclination and no windage adjustment, this mount is intended as a straightforward fixed solution rather than a correction mount. The aluminum construction keeps weight to 5.1 oz., balancing rigidity with reasonable mass for field rifles, target rimfires, and airgun setups where a secure 30 mm mounting platform is the priority.

About BKL Technologies

BKL Technologies originated in Brownsville, Texas, in 1998 and focuses on scope-mounting systems for airguns and rimfire rifles. Its product range includes scope mounts, rings, dovetail adapters, risers, and scope levels, with an emphasis on direct-fit solutions for 11 mm and 3/8-inch dovetail rails. A defining part of the brand’s identity is its patented auto-centering clamping system, developed to keep the mount aligned on the rail as it is tightened.

BKL manufactures its mounts and adapters from aircraft-grade aluminum alloy, and its products are made in Texas, United States. In December 2008, Auto-Numatic Corp. acquired BKL Technologies and moved operations to Fort Worth, Texas. The brand remains closely associated with practical mounting solutions for shooters using rimfire and airgun platforms that rely on dovetail interfaces rather than Weaver or Picatinny rails.
