Mine is a Norinco, Made in China markings, but there are markings "Labanu Inc" from NY (the US importer maybe, or modifier). It originally came with a thumb-hole type stock (which I hated) and was marketed as an "SKS Sporter" with these markings as well on the reciever. Barrel is 16.5"
It has a smaller gas system compared to 20" barrel and the center of gravity is better suited for the smaller size, more towards the mag. I enjoy shooting it, its a handy little gun, but like cz52 said, restricted really limits where the fun could be had.
