Let's build an AR15

The barrels are important. I have that bartlein barrel I spent $600 or so on, but I see faxon and criterion barrels for $330 or so. I got very lucky on my $135 barrel I bought from numrich, it turned out to be a sabre defense barrel from when the feds shut them down. I wish I would've bought several at that price, it's far more accurate than a chrome lined barrel should be, especially in the pencil thin contour.
Sub moa for $135 was a nice surprise.
