I'm wanting to put a Armalite 16" Medium Length barrel on a Bushmaster flat top upper. Will I have any problem doing this, or is there anything that I should be aware of before I have my gunsmith put this barrel on this upper? I have had problems with mixing parts from different companies in the past.
I am unable to look at Armalite's PDF catalog online and they haven't updated their website in a while. Do they offer the 16" Medium Length barrel in a pre ban configuration? Do they offer the Medium Length in anything but a heavy barrel countour? Are their barrels chrome lined?
Any help would be appriciated.
