I have a Kel-Tec SU-16B. It is in many respects an outstanding rifle. It's super reliable and with excellent accuracy using the iron sights. A couple of important things I've learned about it:


  • You really need the sling kit from Kel-Tec. Without it you wont have sling swivel mounts.
  • The charging handle is easy to install incorrectly, which I learned to my chagrin prevents the rifle from firing. Don't do that. The replacement "deflector" charging handle is well worthwhile -- it deflects spent cartridge cases away from you, and gives you an obvious visual clue to prevent it from being installed incorrectly.
  • The optional rubber butt extender adds a little overall length and a lot of shootability.
  • The front post sight on mine could not be adjusted downwards far enough. I fixed it by filing it down (Leatherman Wave saves the day again!) and shimming up the rear sight.
  • The picatinny-style rail on mine isn't lined up quite right with the bore. Forget about getting a red dot sight or a scope working with it. I've read that this is a common issue.
