Pro-Shot Shotgun Port Cleaning Brush 2 Pack

Two stiff wire port brushes sized for shotgun gas ports. One is smaller and one is larger, and between them they cover most of the port sizes found on gas operated guns.

Gas ports run the action, and once they load up with wad residue and carbon the gun starts short stroking and blaming the ammo. A standard bore brush is the wrong shape and the wrong diameter for that job entirely. These are tapered twisted stainless wire, so they reach into the port and scrape it out. Small, cheap, and the difference between a shotgun that cycles all day and one that hangs up on round three.
