Hate to be a dampener on everyones things about refunds and i am in no way wanting to stick up for the seller because i do believe you AC4
but, whats stopping the seller from turning round and saying you were the one that caused all the problems? for example, when you took the eye pipe out, you broke it. And that when he sent it, it was in perfect working condition.
As a buyer, and the lack of the sellers posts, you probably should have asked for more pictures, maybe even a vid??? or even asked for a vouch. Especially due to the price it was being sold. Just not sure how its gonna hold up if you ask the guy for a refund, i have a feeling its gonna end up with him telling you to do one, and you being £75 out of pocket for a fix up. The picture on the thread is blurry as hell.
And you cant sue someone for a personal transaction, especially not this as you have no proof the item was received in the same condition as it was sent, as it isnt 1st hand. If you wanted a refund you, when you opened it and found the 1st problem, you should have taken a picture, left it at that and not tried to clean it up. Its like buying a t-shirt from a shop, wearing it for a day, ripping it, then saying, well, i didnt wear it for the amount of time i wanted to, so give me a refund, fact remains, you still touched it.
Like i said, i dont want to stick up for the seller, and am in no way trying to, but it just seems this is a futile case
Hope he does show up and give you one though, because selling a gun in that state is rediculous
