So I have decided to take the plunge and build my own Ar 15 for .223, So far the lower seems to be coming together nicely but I am at a loss for finding the kind of barrel I would like. So far I have not been able to find a 20" A2 barrel assembly and this is is quite maddening. Browsing through some of the links above I have noticed Arms East has a 16" barrel assembly and the 20" barrel from Questar International but I was hoping some of you guys might be able to help me in my search for a affordable 20" A2 barrel assembly. Any advise will be helpful. Thanks
