It’s not fair to call the STG-556 a knockoff of the Steyr, though it looks like and feels like the AUG. It has some subtle upgrades that we liked, and we had no malfs with it at all. Also, in our shooting, the MSAR was the accuracy leader; however, our action team gave the nod to the AUG.

The STG-556’s port is set up for a righty here, but the MSAR and the AUG allow for left-handed use by installing a left-hand bolt, available from MSAR, and switching the plastic cover to the other side.
Here’s a pretty good look at nearly everything that matters on the MSAR. Front is the tulip-shaped flash hider, the fluted and threaded barrel, the gas regulator, the pull-to-release front grip, the front sling swivel, the charging handle, the tall 1913-spec optics rail, the aluminum-alloy receiver with steel-reinforced bolt slots for more rails, the big grip, and the 10-round magazine in the buttstock.
There’s a lot of interesting stuff on the MSAR, including the hider, which is almost a piece of art. There’s a removable check nut and 1⁄2x28 threads under there for easy installation of a suppressor.
