MG Industries is now shipping a version of the Hydra MARCK-15 rifle chambered in 5.45×39. These guns, called the AK-74 model, use a standard AR-15 configuration, but are able to change barrels and calibers quickly.

This model has a 16″ barrel. It has a flat top design with a Picatinny quad-rail and a low profile gas block. The gun has a M-4 style adjustable buttstock.

The rifle ships with an AR-style magazine made for the 5.45×39 cartridge. The 30-round stainless-steel magazines are made by ASC. I’ve tested a number of 10-, 20-, and 30-round AR-15 magazines from ASC, and I found them to be reliable.

MSRP is $1,299.
