It's more than a NORINCO. It's a Kengs long barreled Sporter with the nowhere rail. As a commercial model, they're kinda rare. I'd sit on $500 if you don't need the ducat$ right now. PAX
PAX, I think you're mistaken about KSI being Keng's. KSI stands for K-Sports Imports out of Pomona, CA. Keng's is shortened to KFS (Keng's Firearms Specialty) and is based out of Atlanta, GA.
KSI = rail to no where, stealth para, parka para, hunters, etc.
Keng's = Nice public security stamped guns & PU scoped guns.
We've always called this gun in the OP's post a KSI Hunter which is a 20.5" rifle with a neutred bayo lug (as opposed to a KSI para hunter with 16" barrel and truly neutered FSB).
