Well I couldn't pass up the $39 upper and $39 Anderson's on Aim Surplus. Will be $125 for the pair once I pay the $20 transfer fee. So my next AR build is under way. After looking through all the available offerings it looks like 6.5 Grendel is a good hunting round for deer and other similar size animals out to 400 yards. Not quite as powerful as a .308 but the build will be about 1/2 the price of an AR-10. And reports of people using it on moose in Alaska means it will take anything I run into in MN! I reload so cost per round is not that big of an issue and prices on the factory rounds are only about 20 cents more than similar .308 rounds right now. As normal this will be a multi month project as my budget allows and what I can come up with via barter(my favorite way to acquire stuff!).
