So, you don’t have $2,000 to spend on a switch-barrel, piston-driven Ruger SR-556? No problem, as Ruger’s AR-556 is a direct-gas impingement carbine that offers most of the features AR buyers are looking for at a little more than a third of the price. Ruger’s engineers looked at the basic AR and came up with their own method of attaching the handguard. The AR-556 comes with a 16” chrome-lined barrel and carbine length gas-system, and although it has a fixed post front sight, it comes standard with a flip-up rear on its optics-ready flat-top upper receiver. There’s a lot of gun for the money here, and the Ruger AR-556 is our NRA Gun of the Week. Watch the video above for more.
