Some can take AK mags or even drums, can be modified to accept optics/NVG scopes, aftermarket stocks etc. Can be converted to fire full auto. More reliable than an AK IMO and as accurate as CZ at ranges up to 200 meters. Sure, it's no match to an AR or even CZ when it comes to dimensions and weight. I still think our government is targeting specific kinds of firearms for the second time for some stupid reason unknown to me. Not like they went after AR's, Valmets or pistols in general like mayor Miller did when CZ and Green became prohibs first time. Same thing is happening again. I really believe it will blow over in 2-3 years.SKS is a 10rd internal mag semi-auto. Can't see it ever going anywhere as it's heavy and not so sporty... you can trick it out but it just adds expense to a dirt cheap firearm.
