The Hawkins Precision M5 DBM Long Action Bottom Metal is a precision-machined billet aluminum bottom metal designed for long action rifles built on a Remington 700 footprint with an M5 DBM inlet. Engineered for 3.715? Winchester Magnum-length AICS-pattern magazines, this bottom metal delivers secure magazine retention with a patented cantilever spring release that resists opening under recoil. It features an integrated barricade stop and a drafted magazine port for smooth feeding and magazine changes, and it includes the necessary action screws and bedding pillars for installation. This configuration makes it ideal for precision and hunting rifles using standard long action magnum cartridges.
