The ammunition carrier includes a stationary carrier body portion disposed about a space in which to retain the ammunition; and a rotating carrier body portion disposed about the space and pivotally. attached to the stationary carrier body portion. The stationary carrier body portion and the rotating carrier body portion collectively form a cover assembly to secure the ammunition. The ammunition carrier further includes a locking mechanism, the locking mechanism pivotally attached to the rotating carrier body portion, the locking mechanism (1) engageable, in an engaged position, with the stationary carrier body portion so as to prevent rotation of the rotating carrier body portion relative to the stationary carrier body portion; and (2) disengageable, in a disengaged position, with the stationary carrier body portion so as to allow rotation of the rotating carrier body portion relative to the stationary carrier body portion.
