Hopefully not too expensive. Get it shooting good and have fun!
Don't feel too bad. I've socked my share of cash into unauthentic rifles, often more than they are worth...but I built them myself from scraps or old mutilated or neglected barn or pawn finds - sweat equity ha!. My satisfaction was worth every penny.
Don't feel too bad. Every time you shoot a good group, your disappointment will be slightly diminished.
