given he had an evaluation thread:
so, lets evaluate this package in detail:
we take our £170 gun: https://www.surplusstore.co.uk/nuprol-delta-ak21-black-6mm-airsoft-rif-aeg.html
mess around with the internals (looks to have had a barrel change at least), but unspecified what's going on, given the specifics aren't mentioned i'd worry about the quality of any work that's been done.
add a paint job which might appeal to some buyers, but will alienate everyone who doesn't happen to exactly like that style.
add a cleaning rod- literally worthless, guns come with them as-standard and most folks are gonna have a couple lying around.
original box- again not much value save for a collectors peice, which a nuprol is not.
4 hicap mags- given most folk will already have mags these aren't worth much to a lot of buyers (especially the mid-cap master race) however in the interests of fairness we'll add that on, given the brand is unspecified i'll be lazy and pick the first result on google for a nuprol hicap at £10 per mag: https://www.defconairsoft.co.uk/product/nuprol-m4-metal-hi-cap-370rnd/
battery and charger- pretty much worthless to anyone who is already setup, but given how this is going so far we'll add that on at £21 for the battery and £10 for the charger (super lazy googling):

gun bag- no info to go on here, so we'll do a quick lazy search and find a gun bag for £20: https://www.patrolbase.co.uk/nuprol-pmc-essentials-soft-rifle-bag?pv=8366
overall i'm getting an equivalent package for £261 brand new, with warranty, without any effort put into shopping around save for ensuring that the item is in stock from a uk seller........
i was gonna do a comparison with other sales in that price bracket, but this post is long enough already.....
