Well Rifter, I certainly do like it alot better. I too have a M-16, and picked up a M-18 in November. The fit and finish is excellent, expecially considering the cost. The recurve blade grind is crisp, and the frost-like finish is really nice. I bought the smaller version because it fit my hand better. I do have bid hands, but I found the large model just too big. The flipper has an extraordinary fun factor, AUS-8 steel is a vast improvement, and the LAWKS system is nice. The G-10 inserts look cool too!
I would say "Go For It". In my opinion, the M-18 is a vast improvement on the M-16. There is really nothing I dislike about it. And once again, for the price, it can't be beat.
