Our Hydra Stripped Modular Lower offers the ability to change Magazine Wells on your Lower Receiver to accommodate whatever caliber you want.  Ideally suited for use with the Hydra® Quick Change Barrel Upper Receiver (QCB-D), where you can change calibers by switching out barrels as well.  This is a Stripped Modular Lower Receiver and ONLY includes the Lower Receiver itself.

DO NOT DRY FIRE YOUR LOWER WITHOUT A MAGWELL THIS CAN RESULT DAMAGE!!!
