Well, I couldn't get a picture to come up so the following is my best guess.
If the synthetic stock is in the same configuration as the wood Featherweight stock, the the stock is a McMillan. I have an XTR in .270 Win. in one of those stocks and the rifle has a 24" barrel. I even have a spare of that stock just in case. AS I couldn't see the picture, my best guess is the person who owned that rifle ordered the stock from Winchester and used it, possibly so that a nice wood stock wouldn't get all scarred up.

That is a great possibility. However, the stock is not a "fwt" stock. If I remember right, it is just an oldstyle early tupperware that came on the sporter push feeds or classic. I'd have to look again, but that is what I remember. The sights did not appear to be factory either. The rifle is/was listed on gunsinternational, if you want to look at it..
