The Spartan Classic Arca Adaptor (SPAR02025R) allows precision rifles fitted with Arca-Swiss accessory rails to interface seamlessly with the Spartan MagnaSwitch™ magnetic quick-detach support ecosystem. CNC-machined from aerospace-grade 7075-T7351 aluminium billet with a hard-anodised black finish, this non-powered mechanical mounting block clamps directly onto standard Arca rails without permanent rifle modifications or gunsmithing. It features a standard Spartan 12 mm Classic magnetic spigot socket, enabling rapid bipod and tripod attachment while retaining locked target mode and traversable panning modes for tracking moving targets.

Key Features

• Magnetic MagnaSwitch™ Interface: Houses a standard Spartan 12 mm Classic socket, allowing instant attachment and detachment of Spartan Javelin bipods, SpringBok systems, Ascent, Sentinel, and Hoplite tripods, as well as Davros heads.
• Direct Arca-Swiss Clamping: Secures firmly along the rifle forend with an adjustable clamp mechanism, requiring no permanent alterations to the stock.
• Dual Shooting Capabilities: Supports both fixed target locking and horizontal traversing to track moving game in the field.
• Billet Aluminium Construction: Machined from high-strength 7075-T7351 aluminium to endure the recoil impulse of standard and magnum hunting calibres.
• Low-Profile Footprint: Provides a rigid mounting point without adding excessive static bulk to the underside of the rifle forend.

• Long-range hunters and backcountry stalkers — adds only 82.2 g to chassis-mounted hunting systems while keeping the 45 mm × 67 mm × 24 mm Arca-Swiss rifle bipod adaptor streamlined during transit.
