The Hawkins Precision DBM is CNC machined from a billet of aluminum. In manufacturing we spared no expense to make this bottom metal smooth and ergonomic. We designed this bottom metal for tactical shooters by incorporating a barricade stop into the front of the magwell, and a drafted magazine port allowing rapid magazine changes. Also included is a patent pending cantilever spring release that will not open under any level of recoil. It uses Accuracy Intl. magazine for short action, you can use double stack or standard magazine depending on your action.  (Magazine sold separately)  The bottom metal is currently on backorder 4-5 weeks.
