Regular price $495.00

Item Description

Original Item: Only One Available. Totally inert and demilitarized according to BATF guidelines with hollow body and inert fuse. This artillery round cannot be converted to an explosive device and is not available for export.

This is a lovely example of a deactivated M309A1 round for the M20 Recoilless Rifle, a high-explosive fragmentation, recoilless, spin stabilized projectile. The projectile has a thin-walled, steel body with a base that tapers, a long internally threaded ogive and an integral, pre engraved brass rotating band. The round still has the original stenciled markings on the side, which read:

It also still has the original production markings stamped into the steel:

REN LOT SOD 500-68 1953 75MM M309A1

The condition is quite nice with much of the paint retained on the exterior, and the original plastic resin housed fuze still unscrews so that the interior can be examined. The shell is fitted into the correct lacquered steel perforated 75mm shell casing, which still has a partial yellow stamped paint marking. It shows the U.S. Ordnance "crossed cannons" cartouche and a 1945 date. The shell casings were often re-used, and this example still has the internal detonator tube that helps spread the ignition charge through the propellant.

The round measures about 29 inches in over all length. A wonderful example ready for display!

M20 recoilless rifle
The M20 recoilless rifle is a U.S. 75 mm caliber recoilless rifle T21E12 that was used during the last months of the Second World War and extensively during the Korean War. It could be fired from an M1917A1 .30 caliber machine gun tripod, or from a vehicle mount, typically a Jeep. Its shaped charge warhead, also known as HEAT, was capable of penetrating 100 mm of armor. Although the weapon proved ineffective against the T-34 tank during the Korean War and most other tanks, it was used primarily as a close infantry support weapon to engage all types of targets including infantry and lightly armored vehicles. The M20 proved useful against pillboxes and other types of field fortifications.
