If you can find a reasonable deal on a Mark II, get that.
Good luck finding a Mark II (blue) for $250. The one's I've seen are running in the $300 + range.Blue - $250
Those bells and whistles can be removed in about 15 minutes.I love my Mark II. I don't like the Mark III. Too many unneeded whistle & bells safety features.
Blue - $250
Then you are left with a hole in the receiver, or you must install a "blank" where the LCI used to be. No big deal if you don't mind the aesthetics, I guess. The mag disconnect is pretty easy to remove also. Many like the new position of the mag release, but I do prefer the heal mag release in a target gun/plinker.Those bells and whistles can be removed in about 15 minutes.
