Firearm assembly with upper receiver incorporating an integral upper rail

Disclosed is a bolt assembly that may include several lands that extend along the forward end of the bolt assembly that occupy only about 1 percent to about 12 percent of the surface area of the forward end. Also disclosed is a bolt carrier that defines a cam path that includes an increased unlock dwell time of approximately twice the unlock dwell time provided by a cam path shaped like a standard M-16 cam path. Also disclosed is a bolt carrier that includes a protrusion at a forward end of the bolt carrier with a bore that extends through the protrusion and the bolt carrier at a substantially constant bore diameter, where the protrusion is sized to be received in the barrel extension extends approximately one hundred thousandths of an inch from the end of the bolt carrier.
