So you buy an extra barrel for an AR15 lower?

yes - - just buy the upper

Just a barrel if you wanted to do a one time change. I just built a complete upper to allow swapping it out. The barrel nut was some kinda fun to get the torque and position done.

I haven’t gotten out to shoot it yet. Gotta do that soon.
