Pyrerealm Gaming converted his airsoft Dragunov SVD rifle to use HPA as power source and it also comes with blowback... "Just a short video showing off my HPA conversion on my airsoft Dragunov, this gun has appeared in a past video on this channel and is going to be featured in alot of videos in the future, this is a small teaser in effect to a proper video that will be coming soon where I fully deck out the Dragunov to make it an extremely effective airsoft gun on the field!"
