What is the benefit to the QRB system? AR-15s are designed to be taken apart. Removing the barrel and reinstalling it separately from your optic will 100% change your poi. I know it says 1 moa or under but this seems pretty silly to me. You are saving maybe 5 inches of room by using that?
Type II bolts/barrels are the most common. I would look for one of these.
As for ammo, cheap steal-cased and accurate really dont tend to go together. Wolf ammo has never been known to be accurate. Also, AR?s were not developed to shoot steel-cased ammo. You may find whatever barrel you buy hates it. If you are not going to reload, I would buy a hodgepodge of ammo and see what shoots best in your gun. Planning on buying bulk cheap ammo is a nice plan. What if your gun shoots 4-5 moa with it?
This is your first gun, buy a complete upper
