Can someone explain to me the advantages of ramping one's 9mm bolt? I've been running a 9mm Colt upper on my standard M-16 for many years now without any kind of problem, and was wondering what the advantages are of ramping the bolt if it already works just fine......

Burnsome-, The story is that the ramping that is cut on the 9mm bolt is like that found on the standard AR-15/m16 bolt and gives an easier push-back on the hammer when a round is fired. When I first started playing with my semi-auto 9mm the benefits of the ramping seemed to be primarily for those shooting full-auto with the Colt style 9mm system. It seems the first noticeable problem when shooting full-auto was trigger slap which could get painful by the end of the day. The next problem was the wear and tear on the hammer parts and the hammer pin holes in the lower receiver. I don't shoot enough ammo (compared to the full-auto folks) to justify having my bolts ramped. If you shoot full-auto with the 9mm upper on your M16 you might want to check the fit of the hammer pin in the receiver to see if the holes have started to get a little oversized or oval shaped. An M16 lower is valuable -- you lucky dog.

JoeBlack ramped one for me - great job and fast turn around. I'd do it again.
