Similar question again regarding receivers

[ronin677]

Hi guys,

 

As most of you know I've been looking for a metal lower receiver for my G&P M16.

 

I am also looking for a upper and lower black nylon receiver for my G&G GR16. Any good ideas on where to pick one of these up in the UK? I want to avoid import tax if I can

 

cheers
