Beretta’s latest AR platform is already getting notice. The easily interchangeable barrel makes the platform ideal for a host of different scenarios. With a simple push of a button, you can alter the ARX 160’s unique reversible ejection, making the rifle suitable to both right- and left-handed shooters. The ARX 160 has a lever in front of the magazine well that is similar in design to a Glock disassembly lever. To remove the barrel, lock the bolt carrier to the rear, pull down on the lever and pull the barrel free of the rifle. As heat is a concern with polymer rifles, the ARX 160 answers it with a ceramic heat shield; Beretta says that you’ll melt the rifle barrel before you damage the polymer. MSRP $2,128.
