Historical Significance
The U.S. M1 81mm mortar was the standard medium infantry mortar used by American forces during World War II and the Korean War. Introduced in the late 1930s and based on the French Brandt mle 27/31 design, the M1 offered longer range and heavier firepower than the smaller M2 60mm mortar. It was widely deployed across all theaters of war and praised for its robust construction and battlefield reliability.
The success of the M1 mortar depended on precisely engineered components, such as the firing pin, which was crucial to initiating the ignition charge on each round. Keeping this key component in top condition is essential for anyone restoring, maintaining, or actively using an M1 mortar system.
Superior Craftsmanship
Our 81mm U.S.G.I Firing Pin is machined from pre-hardened 4140 chrome-moly steel, a high-strength alloy chosen for its durability, resistance to wear, and long service life. Manufactured using modern CNC processes, this part replicates the dimensions and tolerances of the original U.S. military-issue firing pins, ensuring proper function and historical accuracy.
Fitment Assurance
To ensure maximum reliability, each firing pin is fitment-tested with multiple U.S.G.I M1 mortar cups before it ships. This process confirms compatibility across different vintage variations of M1 mortars, giving you confidence in a true drop-in part.
