Thought about the 300 BO for the upper but after a lot of thought, I've decided to go after a complete 6.5 grendel. No on the search for a upper that will have as accurate barrel I can get so I can put a nice optic for distance. This way I have two very good guns in one with just changing out the upper. Need longer barrel to reach out but this will be new to me and not big on doing a build. Expect to drop some coin. so suggestions appreciated.
