Yep, been eyeing 257s on gunbroker past couple weeks (no mtn rifles of course)come on here this AM and VOILA!!
Congrats! You're going to love this. Nicer wood than mine too.
I have a 2-8x32mm Zeiss terra on it and it's a great size for this rifle. I'll upgrade the glass and mounts (to Talley's) eventually but will be sticking with the same size and magnification range.
Good luck with it!
