Leofoto's GS-3 Lightweight Rifle Clamp Mount is a lighter version of the Leofoto GS-2 Support Mount, despite offering the same level of stability. It securely holds equipment without a pre-existing mount port/interface to a tripod. It is fully ambidextrous and features inward-angled jaws that wedge equipment into the clamp for a secure fit. The GS-3 has a double start thread that allows both jaws to move together, providing a center of balance for products between 1-3 inches in width. The textured rubber pads on the GS-3 are designed to create maximum surface area grip and hold equipment securely in place, preventing any slipping or movement during use. This rifle clamp mount can be attached to any ballhead or clamp that accepts an arca-type rail and also can be mounted directly to a tripod via a 3/8" mounting stud.
