In the Season 4 finale of Sons of Guns, entitled, ′Last Round′, the fate of Red Jacket Firearms seems to be in serious doubt. Will Hayden appeared to be losing it as his company struggles with more financial problems, such as being unable to pay invoices. Meanwhile, the local sheriff wants a new sniper rifle for his officers and what was supposed to be a simple project to customize a Remington 700 turned into a competition with Vince Buckles and his new gun shop, Mesa Kinetic Research. To further complicate matters, Kris Ford and his wife Stephanie give Will short notice that they need two weeks off to do an 8-state promotional tour for their new company. So how did it all shake out last night on the Discovery Channel? Is this just the end of the season for Sons of Guns or is it finished as a series? Let′s find out.
