I am really going to try to be nice about this...this "rifle" is one of my pet peeves, though there are several guys who like them. My opinion after careful comparison with REAL Armalite ( and Howa ) AR-180's is that there IS NO COMPARISON. The original Armalite and Howa licensed guns are works of art...the 180B is a cheap imitation with only ONE selling point...it takes AR mags without modification to them. Big deal. Why Armalite didn't do the RIGHT thing and create an improved version of the original that used new manufacturing technologies and welding techniques and retained the original STEEL construction is beyond me. So what if it can't have a folding stock? Use a clever removable one instead. The original 180 is a shooting machine with a great feel to it. If you get a chance, handle a 180B ( which does point very, very well ) then imagine a gun that points that good but feels like a light rifle ( i.e. a real gun ). In my opinion, despite some shortcomings that could have eventually been overcome, the AR 180 was one of the very best rifle designs of the twentieth century. What Armalite has done with it is cheap and tawdry....and in my opinion, rather embarassing.
I am gonna get flamed for this but I stand firmly on my opinion that the 180B is a gun that is just waiting to let you down....stick with an AR....or try an M96 if you have the bucks.
