Re: XT-22 ?
most of what i've found on them when i was going to get one are hit and miss, mostly reports of a few quality issues of stock / hardware fit and a few magazine alignment issues.
others report they are fine for the price, but it's hard to find an objective range report for 100yards or more. most are at 50 yards, which just about any rimfire is going to shoot well at that distance with ammo it likes.
type in xt22 into the search, it'll bring up a few threads on them. there's one in there about the size of the threading being the "wrong" size.
i'm still under the impression that for the price, the xt offers alot, even with the smaller QC issues talked about. in that price range, you are going to have that.
