My buddys SU-16 tactical has been super impressive! he only has maybe 400rnds through it, but so far, it seems respectfully accurate, well balanced, super light, ergonomic, easy to bolt accessory's to, and reliable, ive seen it jam maybe 5 times, and ive been there for all 400rnds. My only complaint with it so far was the trigger from the factory was crisp, but very heavy, like 8-9lbs we measured, I did a trigger job and got the trigger down to 5lbs so now its super nice. But the trigger was an absolute PAIN to re assemble.
Ive handled the folder SU's, would highly recommend the pistol grip one instead, the pistol grip one is fairly robust, but the folder im sure a 12 year old could break over his knee lol SUPER flimsy design.
