I'm looking at one of these (note the bottom pic with the muzzle brake and forend and an optic but not a scope as shown: http://www.kel-tec.com/plr16.html It takes M16 mags, which I have tons of as well as a lot of 5.56mm. I can get one for about $240 from a friend with an FFL. It would be sort of backup on trips for my wife to watch my "six." I'd put one of those BIG red dot optics on it like the BSA or something. Not a lot of bucks into the optic, just enough to do the job. What do y'all think?
