ARCA Rail S – dual-rail adapter for Krait air rifles

The ARCA Rail S is a rail adapter designed for Krait air rifles, combining ARCA-standard mounting with an integrated 22mm Picatinny rail. This aluminum adapter mounts beneath the tank, providing a stable platform for bipods, lights, or other tactical accessories without affecting sight picture or rifle balance.

Construction and materials

Manufactured from aluminum with a black finish, this adapter offers lightweight durability. The dual-rail design features both ARCA (also known as UIT-rail or T-rail) and Picatinny mounting standards in a single unit. The under-tank mounting position maintains the rifle's centre of gravity while adding minimal weight to your setup.

Application and use

This adapter serves precision shooters and field users who need versatile accessory mounting. The ARCA section enables tool-free bipod attachment and adjustment, while the Picatinny rail accommodates tactical accessories like torches or laser modules. Particularly useful for target shooting where quick support changes are needed, or field applications requiring auxiliary equipment.

Integration and compatibility

Specifically engineered for Krait air rifles by AirMaks, this adapter fits the Katran platform. The dual-standard design accepts both ARCA-compatible bipods and any Picatinny-mounted accessories, maximising equipment options without requiring multiple mounting solutions.

Maintenance and lifecycle

The aluminum construction requires minimal maintenance beyond regular cleaning to prevent debris accumulation in the rail slots. The anodised finish provides corrosion resistance for extended field use.
