    Can I use this on an early generation (1998ish) Armalite AR10 upper receivers?

  2. 5 out of 5

    Why anyone would use the ratings area to ask a question is beyond me. Pick up the phone or send an email, for Pete’s sake. I agree with Arthur about Anderson and e-commerce.

    20 inch 243 Winchester Anderson barrel; excellent. Finish was good, head space was perfect, accuracy is as good as any barrel I have, most of which I paid stupid money to own. First 5 shots, 4 in the same hole and one just touching. Zeroed, went to 250 yard steel, 20 straight, all in the center of 6 inch plate. This was all with some Fed 70 grain I just happen to have laying around. I’m impressed with this barrel. I was just trying to use a stripped lower that had no real use. Now I’m thinking, work up a 107 TMK load, and see what it will really do for me.

    PS You must have the Armalite rifle length gas tube. I got mine from Fulton Armory. You need an adjustable gas block. I recommend SLR or Superlative. Buff the chamber and feed ramps. Clean the barrel frequently during break in period, there are many routines, make up your own.
