Looking for another method in using HPA to power a blowback rifle and also generate a good kick as well? Alyan Airsoft demonstrates in a video showing their kit power a WE 999C (G36C) Gas Blowback Rifle. The video shows a full travel of the bolt and also a good kick. The question is always if the base gun can take this power which is sometimes problematic in some HPA-powered blowback rifles in the past.
