You mean the normal variety SVT? Genuine carbine SVT's are unobtanium. There are a lot of creative fakes rolling around, a bunch got chopped into a vague semblance of the original carbines by an importer who took a hacksaw and a blowtorch to a bunch of the Fin capture SVT's a number of years ago.
But you can't go wrong with an SVT... Unless you forget to clean the gas system after firing corrosive. I love mine, love the look of it, love shooting it, it's far more accurate than I had any right to expect. But I don't love cleaning it...
Ok, actually, that's not true. I have a wife and kid. An hour in the evening, alone, cleaning my SVT after an afternoon at the range, really just counts as an extension of "quality time."
You could probably cut the cleaning down to 1/2hr to 45 minutes without cutting any corners. I tend to obsess about my SVT though, and can't seem to get the cleaning done in much under an hour. Can't say I've tried really hard to get it under an hour either.
