Description

This is an original World War II-era U.S. RFX M21 training grenade, fitted with an M204A1 practice fuze assembly. Designed to simulate the weight, appearance, and handling of the standard fragmentation grenades used by American forces, the M21 was an essential tool in safely training troops in grenade deployment and combat readiness.

The RFX M21 grenade body was typically made from cast iron or zinc alloy and painted blue to clearly denote its inert training purpose. Unlike the fragmentation version, the M21 did not contain any explosive filler or fragmentation matrix. It was engineered to replicate the feel and throw of a live grenade while ensuring safety during field exercises.

The M204A1 fuze is a dummy training fuze, often constructed with a functional striker mechanism and a safety lever, allowing troops to practice the arming and throwing sequence with realism. While the appearance and weight mimicked live fuzes, the M204A1 contained no explosive or delay charge, making it ideal for instructional use.

These inert M21 training grenades were widely used at basic training camps and infantry schools across the U.S. during WWII. They are now collectible artifacts that represent the rigorous preparation American troops underwent before entering combat.

Features:

• Original RFX M21 cast body with blue training paint
• Inert M204A1 practice fuze with functional spoon and pin
• Marked for authenticity and training identification
• Completely inert and safe for display

An excellent addition for collectors of WWII U.S. militaria, ordnance enthusiasts, or museum displays focused on military training and preparation during the Second World War.
