AA barrel manufacturer identification?

Is there a way to tell which brand of barrel came on an AA upper. There is an AA 6.5 G upper for sale I am looking at but I would like to know which barrel it is. Is there a way to tell and which ones are preferred. It is a stainless 24" with threads cut in it with a thread protector. That is about all the info I have on it. It probably doesn't matter which barrel is on it they are probably all great but I just like to know exactly what I'm getting.


Thanks, Dan

If they don't tell you who made your barrel, it's probably a Shaw. The Satern option would be worth the money, but you might have to wait a while. I had the barrel you're looking at, but decided to upgrade to a Sabre 24" target. I can't say it was worth the money yet, but it does shoot the higher velocity loads MUCH better. About 2 MOA better. Mine so far has proven to be a 1 MOA barrel, better occasionally. The AA was .5 MOA with ONE load and 3 MOA with 30.7 grains AA2520 behind 123 gr SMKs and Scenars.
