This thing has been around for many years but used a different style of Cap in the past. (Large modern Rifle Primmer) now its a 209 shotgun primmer. It's application. To be mounted in/on a traditional cap lock style of rifle or shotguns nipple snail. Somehow, someway, someone, has Resurrected this antiquated gun part again. It was a problematic part in its past history. Its hard enough for this old timer just getting a cap onto a nipple these days let alone fooling around with this thing when my hands are cold or early morning before daylight.
Good Morning Hawg. You know. I think you should get one of these Hawg. You'd look good a-sport'in one on your rifle. Never have to worry about another wet cap ever._
