Description

The Hydra Stripped Modular Lower is the foundation of the Hydra system, built for shooters who want the flexibility to run different calibers without committing to a single magazine pattern. This lower is designed around interchangeable magazine wells, allowing you to configure the platform to match your setup as your needs change.

It’s ideally paired with the Hydra® Quick Change Barrel Upper Receiver (QCB-D), where caliber changes happen at the barrel level. Combined, the system allows users to switch calibers by changing both the barrel and the magazine well, without rebuilding the entire firearm.

This is a stripped lower receiver only. No internal components, fire control parts, or magazine well are included. It’s intended for builders who want to assemble their lower to their own specifications.

Important Handling Notice

Do not dry fire this lower receiver without a magazine well installed.
Dry firing the lower without a magwell in place can result in damage to the receiver.
