Spartan Precision Equipment Classic Arca Adapter Features The Spartan Precision Equipment Classic Arca Adapter clamps onto Arca-style accessory rails with a clamp width of 1.5 to 1.6 inches giving the shooter a secure MagnaSwitch attachment point on any Arca-equipped chassis or stock. It is compatible with the full Spartan support system lineup including Javelin and SpringBok bipods Ascent Hoplite and Sentinel tripods SpringBok Quad Sticks and Davros heads opening access to the entire product range from a single adapter. Once clamped in place bipods and tripods snap on and off in seconds letting the shooter move quickly between supported and unsupported positions. This makes it a natural fit for precision chassis rifles already built around the Arca-Swiss standard. Machined from hard-anodized 7075-T7351 aluminum the adapter weighs 2.9 ounces and measures 1.77 by 2.64 by 0.94 inches a compact footprint given the strength of its clamping mechanism. The clamp design distributes force evenly across the Arca rail resisting movement during repeated quick-attach and quick-detach cycling in the field or at the range. Because it uses the genuine Arca-Swiss interface it installs without permanent modification to the rifle s forend or chassis. For shooters running Arca-railed precision rifles who want dependable tool-minimal access to Spartan bipods and tripods this adapter delivers exactly that.
