Barrel break-in was created by Itsme
In the manual that comes with a new AR10-A4B,it describes how to break in a Match Barrel. My question is does the barrel on my AR10-A4B need to go through this same process? (It is not a match type barrel.) If so wouldn't the original factory test fire have negated this process? I don't know how many rounds are test fired through each rifle. Any thoughts? :unsure:

Hey dude, good to see you...
As for how many test rounds...I think it is 10 but not sure.
As for the Manual..mine is not a "match" barrel either...but I followed it anyway..as far as what and how it says to do it...mine turned out ok for me anyway...Maybe Uncle A can shed some light on this other wise contact Tim at ArmaLite...he would be able to tell you...that subject came up a while back..oh man..did it start some heat...I would have to say check with the "office" and do what you feel is right...that is the best answer I can give..
Oh I will say though....break it in with "GOOD AMMO" it will help.
I used Hornady TAP, A max and Match 168gr for the first 300 rounds then plinked with the Ultra max...stay away from Winchester Super X, in my opinion...to dirty...
I wish I could be of more help.
Hope it helps....
