That's what Valiant Airsoft did when he put together an airsoft gun made for competitive airsoft events such as speedsoft... "This is my most expensive airsoft rifle! I purpose built this for speedsoft, speedQB, other competition formats to be able to keep up with the crazy HPA and ESG builds that are starting to become more common. I'm not a fan of the paintball style so I decided to turn a LA Capa Customs Void (monk customs) receiver into an overpowered AEG instead. I'm not the best on a rifle trigger but I'm still able to hit 10 RPS and I don't have to worry about HPA lines or tanks. Best of all, it only weighs 3.2 pounds!"
