I could have built it for less, but there were certain parts I spent more on because I wanted more than "basics".
The most costly "upgrade" was the linear comp that was chosen to reduce/eliminate fireballs.
Like I mentioned, the beauty of building is that you get to pick and choose the individual parts you want to use.
I don't have a barrel wrench, so a forum member torqued the barrel onto the upper for me and installed the gas block/gas tube - I did the rest.


Very nice, and a hell of a lot cheaper than if you bought it already assembled . Thank you very much for sharing.
