Desert Tech MDRX with 20" 6.5creedmoor barrel. If you're not familiar, take a look around online. Couple high lights and add-ons to pay attention to: Forward ejection, adjustsble gas block, mbus pro front and rear offset sights, Vortex strike eagle 1-8, BLK LBL handguard with built-in bipod, and strike industries Oppressor muzzle device. I'm not sure on round count- I got it used and it has sat in the safe the couple years because I don't have a good place to shoot.  I know the FDE is hard to find,  and the handguard alone runs close to $600 if you can find one.
