I have a very good condition/low round count Kel-Tec SU-16c 5.56 for sale. Will come with the factory 10 round mag, but takes any AR mag. Ive shot several types of ammo and tried several different brands of magazines and never had a hiccup. Very fun to shoot and folds up nice and compact. I can text or email pictures. Asking $550 shipped/insured to your FFL. text 513-three seven five-1296 for the fastest response or email. Thanks for looking.
