NEF has the rifled sights, smooth or rifled bores. It's the NEF's brother the rifled bull barreled H&R Ultra that only comes with a scope rail.

Avid, are you a real gunsmith or a garagesmith? Whether to shoot it or not? Only you can decide cause it's your body at risk. I would have to recommend lots of prtective gear for the first bunch of shot. Heavy welding gloves and welding jacket type of stuff, maybe your actual head on the other side of a sizeable tree sounds good, too.

Then, take it all apart, clean it and examine it real well for evidence of failure starting.

Hot rods in the garage? Definately! Shotguns? Well I don't know about that.
