BKL 4 Inch Long Tri-Mount Dovetail Riser Mount

• Tri-Mount side dovetails: The riser adds extra dovetail mounting points on both sides of the original rail, making it easier to fit accessories such as lights or lasers without giving up the top mounting position.
• 0.68 in raised rail height: Lifting the optic higher can improve clearance over the receiver and supports a more upright head position, which is especially useful on some airguns and semi-automatic rimfire setups.
• 4 in clamping length: The long contact area spreads support across more of the dovetail, helping the mount sit securely and giving more flexibility when positioning rings and optics.
• Auto-Centering clamping system: BKL’s patented design self-aligns as it is tightened, which helps the riser stay centered on 3/8-inch and 11mm dovetail rails and simplifies installation.
• Aluminium construction: The aluminium body keeps weight moderate while providing the rigidity needed for a stable mounting platform on airgun and rimfire rifles.

About the BKL Riser Mounts Series

BKL Riser Mounts are built for shooters who need a simple way to change optic height or add mounting flexibility on 3/8-inch and 11mm dovetail rails. Within BKL’s lineup, this series focuses on practical rail adaptation for airguns and rimfire rifles, where receiver dimensions and accessory space often call for a more specialized mounting solution than standard rings alone can provide. The series includes several lengths and finish options, allowing the shooter to match the riser to the rifle and the intended setup.

The Tri-Mount versions stand out by adding side dovetails alongside the top rail, effectively turning one dovetail into multiple mounting positions. That layout is useful for rifles that need room for accessories while still retaining a conventional top-mounted optic. Another defining feature is BKL Auto-Centering technology, which is designed to self-align on the rail as the mount is tightened. Combined with the series’ raised profile, these risers are aimed at shooters who want better optic clearance, a more comfortable head position, or a more adaptable mounting platform without changing the rifle’s underlying dovetail interface.

About the BKL 4 Inch Long Tri-Mount Dovetail Riser Mount

The BKL 4 Inch Long Tri-Mount Dovetail Riser Mount is designed for rifles that need more than a simple height increase. Its 4 in overall length gives the riser a long clamping footprint, which helps create a stable base across the dovetail and leaves useful room for ring placement on rifles with limited receiver space. For airguns and rimfire rifles, that extra length can make optic positioning easier, especially when balancing eye relief and accessory placement.

What makes this model distinct is its Tri-Mount configuration. In addition to the raised top dovetail, it provides side dovetail mounting points on both sides of the riser. In practical use, that means the rifle can carry compatible accessories such as a light or laser while keeping the main optic on the top rail. The riser also adds 0.68 in of height above the original rail, which can improve clearance and support a more heads-up shooting posture on platforms where the factory rail sits low.

The mount is made from aluminium and uses BKL’s patented Auto-Centering clamping system, a design intended to keep the riser aligned as it is tightened to the dovetail. With 0 MOA inclination, it preserves a neutral mounting angle, making it a straightforward choice for general-purpose optic mounting rather than built-in elevation bias. This combination of added height, long support surface, and side accessory capacity makes it particularly well suited to adaptable airgun and rimfire setups.

About BKL Technologies

BKL Technologies originated in Brownsville, Texas, in 1998 and focuses on mounting systems for airguns and rimfire rifles. The company’s core range includes mounts, rings, adapters, risers, and scope levels, with an emphasis on practical solutions for dovetail-equipped rifles. BKL manufactures these products from aircraft-grade aluminum alloy, reflecting its specialization in lightweight but rigid mounting hardware.

A defining part of the brand’s identity is its patented auto-centering clamping system, developed to self-align as the mount is tightened. That approach is especially relevant on 11mm and 3/8-inch dovetail rails, where fit and alignment are critical to a stable optic setup. In December 2008, Auto-Numatic Corp. acquired BKL Technologies and moved operations to Fort Worth, Texas, where BKL products continue to be manufactured in the United States.
