Reptilia Corp in Hillsborough, North Carolina, introduced the Arca-S Handguard in September 2026. The rifle handguard has an Arca-Swiss interface formed during machining so a tripod can attach straight to it. M-LOK slots stay available for other gear.

The company made it for users who rely on a tripod to keep a rifle steady, shoot from varied positions, observe, or get a rifle into action quickly.
