Perhaps one of the most customised AEGs these days is the G&G ARP9 AEG which is a good seller for the Taiwan-based airsoft manufacturer. We have seen lots of custom ARP9s and now get to see this ARP9 Beast AEG as featured by Kraken Airsoft... "Today Masai showcases his new custom built G&G ARP9! This thing is super cool!! We love it!"
