| You folks intalled 2 fsb's on 2 different mid-length barrels months apart. The first one was a barrel and fsb I sent in. The other was on an ADCO mid-length barrel with fsb option. I bought the ADCO barrel becuase the first barrel was canted on my Armalite upper. I think something is wrong with the upper not ADCO's work. How often do you guys come across uppers that have this problem? |
