I know I have not seen anything posted on them in quite some time. I recently bought my 2nd one, after foolishly selling my first one. The newer model does not have any iron sights, but if you mount a optic of choice, when you fold it, the barrel rotates, so your optic is sitting off to the side. I got mine new, with a gently used Weaver Holographic red dot, I guess that is what you call it, only about 1 1/2 inches long, had to put it near the end of the barrel on the picatinny rail, but it is fast, and accurate, hard to miss a quart oil can at 100yds. Neither one of mine has had the first hiccup, anyone else have a similar experience.
