Unlike the barrels of some custom T/C barrel purveyors, MGM's barrel profiles fit standard T/C forends.
There are a few other things to consider:
1. If you're willing to go with a 26 rather than a 24 inch stainless heavy barrel, then you can get a standard factory barrel. In my opinion, there isn't a down side to 2 extra inches of barrel. The Pro Hunter barrels are 28 inches long which I believe many find to be unwieldy though I like them.
2. If you went with a tapered barrel with iron sights, you could get a stainless 24 inch barrel. I've found the tapered barrels to be very accurate. Since I use Warne scope basses with QD rings, I can easily remove the scope and use the irons if I want to. I'm not trying to influence your decision but just letting you know about the options.
3. T/C currently has a rebate program that ends on 5/31/10 in which if you buy a new T/C barrel from an authorized dealer, you'll get a $50 rebate.
4. Places to shop for T/C barrels would include Ed's Contenders (a very nice guy to deal with), EABCO and Manventure Outpost (last I looked had many barrels on sale at very attractive prices).
