That's a great pickup jjx! I bet the missing optic and mount pull a couple hundred off the price, but the transit case and paperwork are great to have. I bet that eye piece is a $50+ item by itself though, those things always get lost. It may be this incomplete set is worth more parted out (transit case, paperwork, eyepiece, bipod, + rifle) than it is together as sad as that makes me.
Power Surge is the one to ask about value, I haven't tracked the commercial guns in a good while. I'd guess $700 as is, $900 with the scope and mount.
