Have this posted over on the CMPicon Forums, and figured I would get the opinions of the experts over here. Picked up this carbine a few days ago. It is in the NPM serial number range (44276xx) however there is no manufacture name stamped. The stock has been varnished.

Here is the breakdown of the parts.

So what do you guys think?
Is the rear sight legit?
Could this be a factory correct carbine?
