MGI’S HYDRA: MUTLI-CALIBER FROM ONE LOWER–NEW GUN REVIEW
by DAVE HIGGINBOTHAM on JULY 5, 2014


MGI HYDRA

The 9mm barrel is on the rifle, but the 5.56 barrel can be put on in a matter of seconds.
The Hydra is a mythical creature with multiple heads. It was a snake-like water serpent dragon thing best left alone. Every time you cut off one head, two new heads grew back in its place. The ancient creature is also the basis for one of the most exciting new takes on the AR platform. The Hydra, from MGI, combines a multi caliber lower with an interchangeable mag well and uppers in various calibers. Right now, MGI is making 5.56, 9mm, 7.62×39, and 300 Blackout. That’s only four distinct heads for the Hydra, but there are other calibers in the works.

The method behind the madness is surprisingly simple. The Hydra lower looks just like a typical AR lower, except the mag well has been chopped off. The interchangeable mag wells then slides back onto the lower. The upper can be altered by switching out the bolt, and adding a new barrel. The forend has a clamp built in that secures the barrel inside the upper. The upper then secures the mag well, and so on.

That's a pretty innovative design!

There are quick change AR designs out there and some more user friendly than others but I've not seen one where the magazine well changes out like this one...Intriguing.. :thumbs:

Here is my thinking: There are 2 lowers. One is size large based upon .308, the other is size small based upon the 5.56.

When you buy a lower kit you get a handful of mag well inserts for your lower size. Theoretically you could have a couple of AR lowers and literally have a closet full of guns each a different caliber.

Colt has a very similar design. problem is there is no "mil-spec" for the larger platform.
