It's a great rifle, perfect to stick in a backpack and take to the trails. They are dependable, lightweight, obviously collapsible and take AR magazines.
Unfortunately, some people try and make them into AR type rifles or tactical them out with rails and all sorts of geegaws.
I had one(SU16CA) and enjoyed it immensely. It's a great Get Out Of Dodge rifle, handy as all get out and will serve you well. Just remember to use it as it was designed and not to try and make it into something else.
If you want to transform it into something more tactical, just spend the extra money and buy or build an AR.
“If ye love wealth better than liberty, the tranquility of servitude better than the animating contest of freedom, go home from us in peace. We ask not your counsels or arms. Crouch down and lick the hands which feed you. May your chains set lightly upon you, and may posterity forget that ye were our countrymen.” ― Samuel Adams
