The Hydra is a true modular rifle based on the ever popular AR-15, with a few new twists of its own. The Hydra can be set-up as your basic AR-15 style rifle – firing the .223/5.56mm round, and it comes with a free-floated barrel for added accuracy, as well as a quad-rail handguard and flat-top receiver for mounting your favorite optic, laser, red dot or regular sights. If that’s all the Hydra did, it would be a good rifle, it’s a big step above many of the economy AR-15s on the market, make no mistake about that. What we have in the MGI Hydra is a rifle/carbine that can easily and quickly change from one caliber to another – in about a minute and a half. Yes! You read that statement correctly – the Hydra can change from a plain ol’ .223/5/56mm to a good number of other calibers in less than two minutes, with no special tools.
I’d like one that can switch to 9mm and use GLOCK magazines. That’d really make my day.
