Hello! I recently acquired a Sako L57 in 243 but I'm having a hard time finding any information on it. Its unusual because it has a sporter barrel and target stock. I've found them with heavy barrels and this stock but none with sporter barrels. I know it could possibly be an aftermarket stock but it looks very, very much like many models with a factory target stock. Is it possible that mine is factory? Can you help me with a value? Thank you for any help!
