ARCA Swiss Atlas

The RAT Base is used on our RAT System (Rapid Adjustment Technology) and attaches a variety of accessories to the 1.5″ Dovetail Cut on the BA Chassis System.

This also will attach to the RAT Dovetail Adaptor Plate mounted to the MPA Spigot Mount.

All Atlas Bipods except the 5H will also mount directly to the RAT Base.
