I do not believe that putting gizmos on a rifle makes it a better weapon of war. Putting any reliable magazine fed, centerfire rifle in the hands of a well trained soldier, the soldier will make the difference. The SKS is a fine, obsolete rifle, dressing it up with plastic does not improve the quality of the rifle. If I were fighting in quarters that were so confined that I needed a bull-pup style weapon, I would far rather have a short barrel .12 ga.
I would sure hate to shoot that SKS with the 30 round magazine while trying to keep my head below my cover, but that is just me.
