Thanks for the info so far.I knew it was a risk and will just have to hope it shoots well. It did however do me one very big favour, I now KNOW a certain person is NOT to be trusted and that is worth the £100 or so I might have lost.
I'll clean it up and shoot it. If it shoots well I might put a Pecar on it. The first thing to do will be to get a 7.62 Magazine for it so if anyone has one for sale please PM me.
