Features

• One-piece high-quality aluminium body with hard-anodised protective finish
• Protective film on contact faces to prevent marring and increase grip
• 50 mm fit for scope objective housings of matching outer diameter
• 45 mm clamping length with three-point internal contour for precise alignment
• Front bayonet interface for fast, absolutely repeatable device attachment
• Low-profile, stay-on design that resists recoil from powerful calibres

Precise Hunting Base Clamp 50 mm is a stay-on objective clamp that gives your scope a rugged, 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 a 45 mm section of the objective bell and remains permanently in place. A protective film on the contact surfaces safeguards your scope’s finish while boosting adhesion, so the clamp won’t creep under recoil. At the front, a precision bayonet coupling lets you mount and remove compatible devices quickly, maintaining alignment shot after shot—ideal when switching between day and night setups.

Engineered for Performance in the Field

Purpose-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 your day optic and attached device, keeping the relationship true after hundreds of mount/dismount cycles. The hard-anodised layer shrugs off scratches and oxidation, while the protective film prevents micro-slip under vibration. Once torqued evenly, the clamp is designed to remain on the scope full-time—streamlining your kit and keeping the bayonet interface ready whenever you need it. For rail-equipped scopes, dedicated rail variants are also available.

Precision-Driven User Experience

Installation is straightforward: slide the 50 mm clamp over the objective housing, position it to cover the 45 mm contact zone, then tighten evenly to specification. The low-profile form preserves balance and case clearance. When it’s time to run a compatible clip-on, the bayonet locks in with a positive, indexed engagement that reduces point-of-impact shift associated with off-axis mounting. A smooth exterior and compact footprint minimise snagging around slings, scabbards and vegetation, while the lightweight alloy adds negligible mass at the muzzle end—so your rifle stays lively and accurate.

The Precise Hunting Base Clamp (50 mm) combines a tough one-piece alloy build, scope-friendly contact film and a precisely aligned bayonet to deliver a stable, repeatable mounting solution for front-mounted devices. Match the 50 mm size to your scope’s objective diameter for a secure fit and consistent results from daylight glassing to after-dark work.
