Full product description
ARCA-Swiss Reaper Rail upper assembly for a compatible lower support or mounting arrangement, with locking cant adjustment.
Choosing the right setup
Use this upper assembly to convert or repair a verified Reaper support arrangement for a ARCA-Swiss-equipped rifle. The compact offset design provides room around the magazine area, and cant adjustment helps level the rifle. The upper assembly does not replace all of the functions of a complete lower pan-and-tilt head. Check the lower assembly, threaded interface and any required adapter before ordering. A matching rifle rail profile is essential because ARCA and Picatinny clamps are different.
