BKL Adjustable Scope Mount, 25.4 mm

• Adjustable elevation mount: The BKL Adjustable Scope Mount lets the mount, rather than the scope’s internal erector system, handle elevation correction. That helps preserve usable adjustment range for zeroing and is especially useful on airguns or rimfire rifles with barrel droop or non-standard alignment.
• Auto-centering clamp design: BKL’s patented clamping system moves both sides evenly as the screws are tightened, helping the mount stay centered on 11 mm and 3/8-inch dovetail rails. In practice, this supports more consistent scope alignment and reduces the need for improvised fitting.
• Six-screw, 2.5 inch clamping length: A long contact surface and multiple clamp screws spread recoil and handling forces over more of the rail. The result is a more secure hold for hunting optics and target setups that need to stay in place over time.
• 1 inch scope compatibility: Built for 25.4 mm (1 inch) scope tubes, this mount suits a wide range of rimfire and airgun optics without adding unnecessary bulk. It is a practical choice for traditional riflescope setups on dovetail-equipped rifles.
• Aircraft-grade aluminum construction: The aluminum body keeps weight down while maintaining the rigidity needed for repeatable mounting. That balance is valuable on lighter rifles where excess mount weight can affect handling.

About the BKL 1 Inch Mounts Series

BKL 1 Inch Mounts are the company’s 200 Series, developed for 1-inch scope tubes used on 3/8-inch rimfire and 11 mm airgun dovetail rails. The series is aimed at shooters who need a secure dovetail mounting solution for airguns and rimfire rifles, where rail dimensions can vary slightly and conventional mounts do not always center themselves cleanly. A defining feature across the range is BKL’s patented auto-centering system, which moves the clamping legs equally as the screws are tightened so the mount aligns itself on the rail.

The series covers more than one style of setup, including unitized mounts, separate rings, offset versions, high configurations, and drop-compensated designs. That gives the line a practical role across field rifles, target airguns, and compact rimfire builds. Aircraft-grade aluminum alloy is central to the design philosophy, keeping the mounts light without giving up the rigidity needed for stable scope installation. Another characteristic of the series is the clamp-spreading feature, which allows the mount to be opened for installation on dovetail rails that would otherwise be difficult to fit. In use, the range is built around straightforward installation, secure clamping, and compatibility with the dovetail systems commonly found on airguns and rimfires.

About the BKL Adjustable Scope Mount, 25.4 mm

The BKL Adjustable Scope Mount, 25.4 mm is a unitized 1 inch dovetail mount built for shooters who need more than a fixed-height solution. Its main advantage is the adjustable design, which provides over 30 MOA of elevation correction. In practical terms, that makes it useful for rifles with barrel droop, for setups that run out of internal scope adjustment too early, or for shooters who want to preserve more of the riflescope’s own elevation travel for longer distances.

This model combines that adjustment with the mechanical stability expected from a one-piece mount. It uses six clamping screws across a 2.5 inch clamping length, creating broad rail contact that helps the mount stay planted on 11 mm and 3/8-inch dovetails. For airgun and rimfire use, where rail dimensions can vary and recoil behavior is different from centerfire rifles, that longer clamping interface is a practical benefit. BKL’s auto-centering clamp design further helps the mount settle evenly on the rail as it is tightened.

The mount is made from aluminium and keeps a relatively low profile for an adjustable system, with 0.825 inches from the bottom of the mount to the bottom of the scope tube. It also includes side rails for accessory mounting, which adds flexibility without changing the basic role of the mount. For a 1-inch hunting optics or target optics setup on a dovetail-equipped rifle, this model is designed to solve alignment and elevation issues while keeping the installation solid and compact.

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 mounts, rings, dovetail adapters, risers, and scope levels, all built around the company’s patented auto-centering clamping system. That design is intended to self-align as it is tightened, which is particularly relevant for 11 mm and 3/8-inch dovetail rails where fit can vary between rifles.

The company manufactures its products in Texas, United States, and uses aircraft-grade aluminum alloy for its mounts, rings, and adapters. BKL has built its reputation around practical dovetail solutions rather than broad firearms accessories, which gives the brand a clear specialization in this category. In December 2008, Auto-Numatic Corp. acquired BKL Technologies and moved operations to Fort Worth, Texas, continuing the company’s focus on mounting systems for precision airgun and rimfire applications.
