The Leofoto GSP Series M-LOK Quick Release Plate is Arca-type compatible and features several removable safety-stops to assure the rifle stays stable when shooting. The safety-stops and screws are all stainless steel and the plate is CNC machined from T6061 and hard anodized for durability. A hollowed out design makes the plate relatively lightweight and via the threads and included screws, the plate can be secured to the M-LOK handguard of compatible rifles. You can then mount the rifle on Arca-type ball heads and other supports. Leofoto M-LOK 140mm QR Rifle Support GSP-140
