The Caldwell 123904 Spare Mount Black Picatinny For AR Brass Catcher is a compact aluminum rail mount designed specifically to work with the Caldwell Pic Rail Brass Catcher system. This low-profile block clamps to any standard Picatinny rail on AR-15 and similar rifles, giving your brass catcher a secure, repeatable attachment point without interfering with optics or other accessories.

By installing spare mounts on multiple rifles, you can move a single Caldwell brass catcher from gun to gun in seconds, making range sessions cleaner and brass recovery far more efficient. The mount includes the necessary fastener hardware and is fully adjustable along the rail to accommodate different scope and handguard setups. It is an ideal accessory for reloaders and shooters who want to keep their firing line tidy while relying on Caldwell’s proven shooting gear design and consistency.
