Here is some pics of a new SKS-D that I have acquired. Comparing to my other D, I immediately noticed a few differences.
The gas tube is shorter. The barrel is also 0.5" shorter. No bayonet lug, and this was not ground off(looks factory, cnc machined). Stock also has no cut out for bayonet.
The front ferrule also seems in a different place, now the stock is super tight and doesnt fit properly in the rear on this stock.
Overall fit and finish are the same. My question to all the SKS-D gurus, how many variations is there? These are the only two I have examined closely and was surprised. I know of the later D's with the mag release that looks much like the regular sks but never seen these differences before.
