Hi Guys, New guy here! I have this rifle ordered and coming Friday for pickup at my local gunstore and I'm trying to order the correct base and rings for it. The scope I ordered is a burris mtac 6-20x50. From what I'm seeing the bases are calling for a "flat" rear or "round" rear base....I would like to order a one piece egw 20moa base and not sure what to buy here without seeing the rifle first! Itchy to get everything ordered so I can start to break in the barrel Sunday! Any help would be appreciated as well as suggestions for base and or rings! Thanks!
