12 gauge inserts
IInserts reduce the size of the chamber to fit the smaller-gauge shells, allowing the shooter to safely fire 20, 28 and .410 ammunition through 12-gauge barrels without any appreciable change in the weight or balance of the firearm.
Shooting smaller gauge shotguns is also becoming more popular with bird hunters, who are seeking the fine handling ability of a 12-gauge firearm without the recoil of the 12-gauge ammunition. Taming the old thunder-buster with 20, 28 or even .410 loads is quite a promising prospect for both veterans and beginners alike.
Great for teaching kids with out the price tag of another gun.
