The M29 is an American-produced 81 millimeter mortar. It began replacing the M1 mortar in U.S. service in 1952 being lighter and with greater range. It was subsequently replaced by the M252 mortar in 1987. Variants included the M29E1 and M29A1, adopted in 1964. These were produced with a hard chrome-plated bore to prolong barrel life and ease of cleaning.
