M27 105mm Recoilless Rifle
Recoilless rifles are capable of firing artillery-type shells at velocities, and with an accuracy, comparable to those of standard guns, but almost entirely without recoil. This RCLR is a breech-loaded, singleshot, man-portable, crew-served weapon. It can be used in both antitank and antipersonnel roles.
The US Army used 105 mm M27 recoilless rifle in the 1950s. This rifle, a 105mm weapon, proved to be lacking in accuracy as well as reliability and was soon put out of service. Soon, the M27 was redesigned as the M40 and, to avoid confusion and to also prevent use of the M27 ammunition still in stocks in the new weapon, the M40 was classified as a "106mm" weapon.
