Abstract: A suppressor mount device can include a first end having a barrel coupling feature adapted to couple the suppressor mount device to the barrel of a firearm. The device can further include a second end oriented opposite the first end along a bore axis and a suppressor coupling feature adapted to receive and retain a firearm suppressor. The device can further include a bore forming a void along the bore axis within the suppressor mount device, the bore adapted to allow passage of a projectile along the bore axis from the first end to the second end. The device can further include a reaming feature formed on an outer surface of the second end adapted to engage an inner surface of the firearm suppressor. The reaming feature can include a channel which is at least partially oriented non-parallel and non-perpendicular to the bore axis.
