- Based on the company’s Hydra, this version is a belt-fed .223 Rem. chambered model.
- With this configuration, the Hydra is using Colt magazines to chamber 9 mm cartridges.
- Here the Hydra has been converted to use Glock magazines for .45 ACP.
- Here’s another look at the .45 ACP configuration with a Glock mag.
- If you want a little more capacity in your .45 you cen even run Grease Gun magazines.
- The MGI Hydra Marck-15 Modular Rifle is the basis of the company’s system, that allows you to use a variety of chamberings on a single platform.
- How about running 7.62×39 mm through the Hydra using an AK-47 magazine?
- Obviously, this versatility is only possible by changing bolt carriers….so they are available from MGI.
- To facilitate different magazines, accessories are available to alter the lower for the Hydra.
- And of course, different barrels and gas block locations are also required for this kind of versatility.
