I’ve owned these inserts for a number of years. Most recently I used them in an elegantly beautiful sidelock ejector with dangerously thin barrels. I became so enamored with 28 ga performance that I finally bought a 28ga shotgun. These inserts were designed to be used with O-rings for a perfect fit, but I found that Teflon tape works fine and is available everywhere. They work perfectly with ejector guns. $400 shipped.
