SU16 is my current favorite 223 — enough that it is my house gun. Mine is very heavily modified with Keltec and Red Lion parts, equipped with light/laser, red dot and a sound suppressor. The full-up weight is probably 50% more than this base model, folding receiver sport-utility carbine. But in its original form, SU16 is light, has a very long sight radius, folds up for storage with two 10rd or one 30rd magazine in the stock. And it’s a clean-running piston design.
