The Picatinny MARC Plate is a reversible mounting plate for the modular shooter. From direct mounting a Picatinny forend to a tripod head, to mounting a laser range finder to a picatinny spotting scope cage. This unique mounting solution will increase equipment flexibility of the modern outdoorsman. The Picatinny MARC Plate has been designed to mount to both (1.5”/38mm) Arca-Swiss tripod clamps and be compatible with legacy Manfrotto tripod heads that use RC2/200PL attachment plates. The Patent Pending design prevents horizontal movement with Manfrotto tripod heads, and accommodates for Arca-Swiss plate retention slots.
