Hi eyebull - apologies for the very late reply, I've not been here for a while! The Camden range is called 'Alpha Guns London' and is on Camden High Street, located in a downstairs basement. I went in there to check it out, the venue is quite small, the shop sells two-tone airsoft guns and has an all-enclosed range. Their website is here:
