In this video by L'Antre Du Dingo, Ding reviews the Wolverine HPA Havoc engine within a Genesis Arms Gen-12 Dracarys replica, a collaboration between Genesis Wolverine and EMG. The replica, constructed from machined aluminum, is a semi-automatic shotgun that uses Gen 12 magazines and features a TTI handguard and BCM furniture. Its HPA system allows for adjustable firing modes, shooting eight BBs at once to simulate a shotgun spread. He mentions its effectiveness and fun factor in CQB scenarios, emphasizing responsible use and encouraging fields to understand its capabilities before banning it.
