Thanks Joe!!
There is a conversion to extractor, but it's not positive like the current production extractors, just a spring driven extractor. Best advice is in the FAQs, polish the chamber and tune the ejector a little to provide more pressure on the ejector claw, 99.9% of all stuck brass is barely stuck, those that I've had from too hot of load come out easy, I've even had some pop out while I was retrieving a rod from behind the shooting line!
If it's really sticking bad after you've tried all the fixes, you may be loaded too hot, or have a defect in the chamber. If it's a factory fitted barrel, H&R will fix the chamber or replace the barrel with an extractor barrel.
