The AR-31 shares the design and the accuracy of the highly acclaimed AR-30A1 bolt-action rifles, but with three major differences: the AR-31 is chambered in .308 Winchester, it is a short action version of the AR-30A1 and it accepts Armalite's AR-10B double-stack magazines. That means you can use 5, 10, 15, 20 and 25 round mags with the AR-31. The barrel has an adjustable cheek piece and buttstock. For sub-MOA accuracy, think ArmaLite's AR31.
