This is the SKS Pug I with the 10 inch top pic rail mounted for shooters who prefer flip up iron sights for their sighting system. Fits the Russian Chinese Norinco and the Yugo SKS barreled actions. Of course magnifying optics can be used if required, but the irons are perfectly setup for this system.
The Pug is suitable for California and other states that do not allow detachable mags.
It is also suitable for the shorter barreled Paratrooper models with fixed mags, and those with AK fitted mag set-ups.
