Original Item. Only One Available. The MK 108 is a 30 mm caliber autocannon manufactured in Germany during World War II by Rheinmetall‑Borsig for use in aircraft. The weapon was developed as a private venture by the company in 1940 and was submitted to the Reichsluftfahrtministerium (RLM—Reich Aviation Ministry) in response to a 1942 requirement for a heavy aircraft weapon for use against the Allied heavy bombers appearing over German-controlled regions by then.

The MK 108 was quickly ordered into production and was installed in a variety of Luftwaffe fighter aircraft. It saw first operational service in summer 1943 with the Bf 110G-2 bomber destroyers and in the Bf 109G-6/U4.

Unloaded or dummy grenades, artillery shell casings, and similar devices, which are cut or drilled in an BATF-approved manner so that they cannot be used as ammunition components for destructive devices, are not considered NFA weapons. This example is in total compliance and is NOT AVAILABLE FOR EXPORT.

This is a great example of a 30mm aircraft round for the Mk108 cannon. It measures roughly 8” in overall length, and retains some yellow paint with a green and red band on the projectile. The fuze is stamped zz 1589A rcr 3 44 Waffenamt 26. This denotes a 1944 date.

The bottom of the casing is stamped aux 44 754. This denotes 1944 manufacture by Polte-Werke, Werk Magdeburg, a maker of ammunition. The shell is in fair shape with some cracking along the top edge as shown, and the projectile cannot be removed currently. 

A great example, ready for further research and display.
