Probably the worst sales post I've ever seen, gives a whole new meaning to the word lazy 

Out of curiosity is the Amoeba stock? You may want to detail what is included attachment wise. Also you may want to reconsider your pricing as these can easily be had for £150 - £175 brand new.
 
The shotgun looks as though it's a Cyma. You may wish to clarify if it's entirely plastic or if it's metal (obviously some parts will be polymer).
 
edit: I'd also suggest confirming the manufacturer for the LVOA and what has been altered internally (if anything) beyond the addition of a Gate Titan. It's also wise to disclose if the work was done professionally and if you have supporting documentation.
 
Best of luck with you sale.

Correct me if I'm wrong but aren't these retailing for £90 from those crap bbgoonz sites? 

Yeah, I'd certainly be interested in a few bits you've got here if you were to list them separately as opposed to a bundle deal.
