Hi guys im new to the AR world as I have never had one before. I am wanting to try one out. I already have a 6.5 grendel in a howa mini so for the sake of keeping everything simple for now I would probably go with that cal. Can someone give me some info on what kind of upper and lower I should look for. I know that kind of stuff is alot personal preference butt I guess I am looking for some recomendations.

Thank you for any help you can give
