Caveat emptor.....i would never deal with someone with less than 500 posts that I can't meet face to face....
Does the safety not work at all when you move the safety..as they are not automatic on the lightning.
What other damage is there other than the stock scratches..is the stock cracked at the front ...just in front of the screws..also put a straight edge on the barrel .see if it's true...lightnings are prone to being fired open and then lots of damage is caused...
Hopefully you will get a refund..I never when i bought a scirocco 2000 a few years ago for £280 ..good luck
