Features

• One-piece high-quality aluminium body with hard-anodised finish for wear resistance
• Protective film on contact faces to prevent marring and boost grip on the tube

• Low-profile form factor that remains on the scope without affecting handling
• 45 mm clamping length with three-point internal contour for precise alignment
• Front bayonet interface for fast, absolutely repeatable attachment of devices

Precise Hunting Base Clamp 51 mm is a dedicated scope-objective clamp designed to stay mounted on your optic and deliver a robust, repeatable interface for front-mounted accessories. Machined from a single piece of high-quality aluminium and hard-anodised for corrosion and wear resistance, it grips over a 45 mm section of the objective housing. A protective film on the contact surfaces protects your scope’s finish while increasing adhesion, so the clamp stays put even on powerful calibres. At the front, a precision bayonet provides fast on/off for compatible devices with stable, repeatable alignment—ideal when you want to swap gear without losing setup.

Engineered for Performance in the Field

Built to handle real recoil and weather, the Base Clamp uses a special three-point internal contour to self-centre on the scope objective. This geometry improves parallelism and alignment between optic and attached device, so the relationship remains true after hundreds of mount/dismount cycles. The hard-anodised layer resists scratches and oxidation, while the protective film prevents cold-weld and micro-slip under vibration. Once torqued correctly, the clamp is designed to remain permanently on the scope—streamlining your kit and keeping your interface ready at all times. The result is a stable, corrosion-resistant base that won’t creep, even on magnum hunting rifles.

Precision-Driven User Experience

Installation is straightforward: slide the 51 mm clamp over the objective bell, position the 45 mm gripping section, and tighten evenly until secure. The low-profile, stay-on design preserves balance and clearance in scabbards and cases. When it’s time to run a compatible front-mounted device, the bayonet locks in with a positive, repeatable engagement—no re-indexing or guesswork. The precise alignment reduces point-of-impact shifts associated with off-axis mounting, while the smooth exterior and compact footprint keep snag risks low around pack straps and vegetation. For rail-equipped scopes, dedicated rail versions are available separately.

If you need a durable, repeatable and scope-friendly mounting interface, the Precise Hunting Base Clamp (51 mm) delivers. Its one-piece aluminium build, protective contact film and three-point alignment give you a stable base for clip-on devices while preserving handling and finish on your glass. Choose the 51 mm model to match your objective housing for a secure fit and consistent results in the field.
