This is my Kel-Tec PLR-16, a long-range pistol chambered in .223 Remington. It is similar to an AR-15 pistol, but it does not use direct impingement, relying instead on a short stroke piston system. It also does not have the buffer tube the AR pistols typically do. It has been customised to an extent...note the 30 round magazine and the compact foreend with the picatinny rail, both nice upgrades I think. I added a holographic reflex sight, BSA's multi-reticle version, which has worked out great. And most recently, the soft case (on which it is sitting) and the Yankee Hill Machine flash suppressor were given to me by my father-in-law for my birthday...quite nifty. I *could* modify it further with accessories on the underbarrel rail (such as a laser, or a tactical light) but I don't really need that at all. And a vertical foregrip would put this into a restricted class of weapons so I'll happily skip that.
How about a better view of the flash suppressor and reflex sight:
I'm looking to get this back out on the range again soon. It doesn't kick as much as you expect...the weight absorbs a good amount of recoil. Certainly nothing like the recoil you'd expect from something like this:
