Pretty interesting. I have a bunch of these rifles purchased through both Wally World and my LGS. I've pulled some bbls and rechambered the rest. I might even have an 'untouched' one. ha ha. I do have the stock bbls stored in the reloading room.

However, It's hard to believe that WM would have requested and received a special twist. What would be the purpose? CSI?? Interesting.
I do have 1:7 twist, but it's a Colt HBar......... I just always 'assumed' that the Axis 223s were 1:9......
