| Was I the only one that cringed when he said "Lathe" something? Not to poke fun, I got laughed at 10 years ago for saying that very thing. It should be "Turn" something.
As far as the freak inserts go they can be a benefit if you have to use the very small paint. The stock barrels are actually what used to be considered somewhere in the medium bore range, but now tends to be on the large size. The id should be .690" +/- .003. One thing to keep in mind is the stock AT10 barrel is only 6" long. I don't have a freak insert in front of me but I tend to remember them being nearly that long by themselves.
I have been told that Northern Command can even get you ones that will still use the unisizer, although they may be special order items. |
