No there is no QLA or recessed muzzle, but that does not make loading sabots or conicals anymore difficult. I load them all the time in the rifle. In fact I prefer that they do not have one. All my old Thompson Center Rifles did not have the QLA and I have been loading roundball, conicals, and sabots in them for years. I never saw it as a problem.

Whether they have a barrel to fit your PA Hunter I do not know. If you can get to a phone talk to Kerry. She can answer all your questions and set you up with what you need.
