I've known this was in the works for a while now, but saw where SilencerCo recently announced their integrally suppressed Maxim 50 muzzleloader. Essentially is a Traditions Vortek Strikerfire 50 cal muzzleloader that they have a silencer on and since it's permanently attached, you can buy it like any other firearm. No NFA fees or wait time. For now they don't have a 'northwest' edition so I have no option to try one but it seems like it might be fun one to shoot.
