Could say you living unto you're username. New member with no feedback trying to sell a whole collection for £3,300. Are deliberately trying to get into the "Airsoft Dreamers" Thread?
Seriously and on the off chance you're genuine your gonna struggle to sell a package like that. Not bothered to add it all up, may be a good deal, but it just such a big price. Finding some one with. that sort of cash that is gonna want exactly that, unlikely. You'd be far better of breaking it up into smaller lots, individual guns and then one for gear.
I would mate, having looked again when it does the Mags are worth maybe £20 each and you may sell the receiver body for a fe w quid as it has HK Trades.
Picture shows two Gen 5 slides just to confirm the one with comp is the WEII Tech
What is the boxed Gun 5 and does it have any internals and Sight plates?
Where is the TM Gen 4, or was that type is it the Gun 5 below the WEII Tech one.
Also you mention a Detonator Slide?
This add makes no sense, the boxed one from the quality of the trades to me looks like it could be. detonator.
