Overview

Built for competition-style shooting, this support-bag arm is intended to help keep a bag positioned and ready when shooting from improvised rests. The included ARCALOCK clamp allows mounting to Area 419 ARCALOCK rails or most standard Arca/RRS 1.5" dovetail rails, giving it a practical fit for a range of compatible setups. It is designed for use with RailChanger-equipped support bags, which can hang from the arm for hands-free support over barricades, cattle gates, and similar obstacles. Made from 6061-T6 aluminum with a Type 3 hard coat anodized finish, it offers a purpose-driven setup for shooters who want a more organized support-bag system without extra complexity.
