Thanks for the welcome. I am a gun guy, but do not have an AR, though it's something I've toyed with for decades. When I was in high school I really wanted the Jager AP 74 - .22 clone of the Colt SP 1 . . I still like them, but I think the Colt Tactical is a better firearm. (Umarex made a nice Walther P22 that I own.) That's probably why I would like to get the Colt tactical M16 rifle, though they seem to be a whole lot more difficult to find than the M4 carbine. . . I have not ruled out an actual AR, but I'm in the stage of life where my net income is not reconciling with my gross habits. . . so as I think about it, the Colt Tactical seems like my best course. But I'd really like to put triangle handguards on one.
