They are pretty tidy looking compared to some bubba jobs I have seen regarding the front sight. It's pretty cool to have a bayonet, a brake...and the option to go straight pull bolt action for a bit more horsepower.
I imagine the reason the gas shut off was left was to use up old stock of gas tubes that require it, since they went to the trouble of modding the front sight to not look like someone just took off the ladder.
If I were trapped in one of those states...I would be happy to have it. It would be nice to have an essentially brand new SKS option on the market more often. It sure would be nice if we could get the new commercial Russians.
