Aero Precision M4, AR-10. 7.62x51, .308. Has only had about 10 rounds through it. Bipod, scope, and 2 20 round mags included. Like-new condition, no scratches. Extra clean. I just don't have any need for it anymore. Must be willing to meet in person in public with ID. No private shipping. Could ship through a dealer at your expense.  Also, about 850 rounds are available at an additional cost.
