About 5 years ago, had my teenage years mauser deer rifle rebarreled to 257Roberts with an A&B barrel. For a low priced barrel it was surprisingly accurate. Since then, I've had at least 5 A&B chromemolycenterfire barrels installed and none have disappointed me as far as their accuracy. They could have a better exterior finish, but a little work by me takes care of the finish. Two A&B barrels ago, I used an elderly retired machinist, who has worked on guns as a sideline for over 45 years, to install a barrel. An experienced licensed gunsmith nearby often consults with him when he has a problem. Anyway, he had a very bad opinion of A&B barrels due to something he'd experienced with them years ago. After the second barrel install for me, guy told me he'd changed his opinion on A&B to the positive....that for being low priced it was a darn good barrel.
I don't hunt, just shoot paper about once a week at a range I'm a member. If I was willing to invest in an expensive custom benchrest rifle build, then I'd probably go with a better regarded higher priced brand....but for my shooting needs the low priced A&B barrels had done quite well for me.
