Good stuff. There's lots I would like to see changed about the SU16, but the truth is KelTec designed them to meet a demand in a certain portion of the US market, and they do that exceedingly well. I do love mine though. There's nothing on the market that even remotely compares to it in terms of weight and function.
I thought the factory iron sights were surprisingly good - You're right, they're not easy to adjust, so clearly not made for dialing wind/elevation. But the basic model has a nice long sight plane. Before I mounted an optic I was consistently getting 3-1/2" to 4" three shot groups at 100yds with surplus Chinese ammo with the irons, from a casual rest. I think the best I ever got that ammo to work back in the AR days was 3-1/2", so I'll consider my SU16 to be pretty darn good with that ammo. I'm working up handloads just to see what it is capable of - There are some reports of shockingly good accuracy out there.
