Gel Ops V2 shows this 3D Printed Flashbang that can be used for airsoft that utilises cap gun rounds... "Flamingo Custom Works has come out with a realistic and effective flashbang that works on concrete and outdoor surfaces! It uses caps which are cheap and readily available which makes using the flashbang even that more fun knowing it wont cost an arm and a leg to throw it again. It has a very sturdy and lightweight body that they are still working on improving, but even with the current model it is very durable and effective especially in indoor CQB style matches! I would 100% try this flashbang out as its cheap and cheap to use and will definitely help you get a few hits in your next match!
