if you want just a 54r shooter you are better of getting a vepr in that caliber.
SVTs are finicky, have not very good steel in the barrels, suffer from vertical dispersion because of the muzzle extension and the way it's engineered. gas plugs on some of them are corroded and unable to throttle down amount of gas which causes you rifle to get beaten by excessive BCG impulse. i mean it's great collective gun and i love it, but just for the purpose of having 54r semi auto where no conductibility wanted then Vepr is the most logical way to go. it's an outstanding quality rifle, built like a tank, will accept almost ALL optics accessories for regular AK, not to mention it's chrome lined and barrel technology is almost 50 years ahead of old war-time barrels of any SVT
