Yep - now considered primitive under the MS game laws. They have continually modified what they deem "primitive" firearms with the changing times to allow even more opportunities for their sportsman who wish to utilize the primitive seasons. The NEF firearms blazed the way for modern metallics being allowed in single barrel/swap barrel hammer guns, which opened the door for Contender, G2 and Encore using any cartridge over 38 caliober at first but now 35 caliber, including bottle neck and not just straight wall cases. And they allow them to be scoped. Not primitive in the sense any of us old traditional muzzy and archery hunters see primitive by any means, even less so than modern in-lines, but they all are legal in MS now.
FWIW
