FWIW, I have a 257AI ULA, an early one made in 86. I bought it at an auction for a good price, probably because it is an AI and the price reflected that...something to consider. This particular rifle does not feed the fat AI case very well, but does feed regular Bob cases all day long, would have had the feeding corrected but if this barrel ever wears out its going to be a Roberts.
IMO the AI appeal wears off quickly when you consider the extra work required to get good AI brass and the velocities that the regular Bob can get.
