It seems that prices are coming back to 'Normal' over there Matty, an Innova rear sight struggled to achieve £40 not long ago.
As i've stated previously. Some punters get 'Auction Fever' and bid silly money for items, that's when they pay £60 for a rear sight and £80 for a aluminium silencer adaptor, these prices are the exception and certainly not the rule, but if your a seller and in the right place at the right time your laughing.
