This is part 1 of the GHK URG I V3 upgrade as done by the Middle Aged Gamer... "After having the GHK V3 URG-I 10.3" GBBR now for a while its time to make some changes. In this video we change out the stock and grip and install an official V3 UK friendly NPAS nozzle from GHK/Samoon. with these changes the URG-I will be more comfortable to the user and run in it natural environment of CQB but have the ability with a simple twist of the tool to go outdoors too."
