shoot 45 ACP cal. in 16 Gauge

Allows your 16 Ga shotgun to shoot 45 ACP cal. ammo. It is simple and easy to use. The insert simply drops into the chamber of your single shot or double barrel shotgun and the smaller diameter ammo fits inside of it. It will work in a bolt action too if placed in the chamber by hand. (They don't work well with auto-loading or pump shotguns). See listings for other sizes. With these smooth bore shotgun Chamber Conversion Inserts, you can maximize the use of your shotgun by being able to shoot other gauges and even rifle and pistol calibers in your shotgun. Shoot smaller gauge shells, rifle, and pistol ammo in your shotgun. The machined steel chamber conversion insert allows smaller (cheaper) ammo to be shot. The discharged shell will slide out of the insert easily. The rifle inserts are not intended to take the place of an actual rifle, but the shot-shell inserts do hold a good shot pattern. They are handy to have to increase your ammo options should ammo become scarce or unavailable. Length: 2 3/4" long.
