We are selling our WWII German 30mm Beltfed Mk108 automatic cannon. This cannon is transferable and was dewated by cutting the barrel chamber with a torch. The barrel is not repairable, but I have a good barrel included in the price. I am also including a German tech manual on the gun for $12k delivered.
The MK 108 is a blow-back operated, rear-seared, belt fed 30mm automatic cannon using electric ignition and is charged and triggered by compressed air. It has a very short barrel, which gives the MK 108 a low muzzle velocity of 500-540 meters (1640-1770 feet) per second. The maximum rate of fire is 650 rounds per minute.
An interesting feature is that neither the barrel or receiver move in recoil, the entire force of firing is absorbed by the rearward movement of the bolt against the driving springs, which bufferes against the recoil. No locking mechanism is needed, because by the time the fired round had overcome the inertia of the firing bolt, the round had left the barrel and the pressure has dropped.
There were two main types of ammunition for the MK 108 to use, a 30mm high-explosive self-destroying tracer ("M-Shell" or "Mine-Shell") and a 30mm incendiary shell. The first type was designed to cause a maximum blast effect by combining a very thin shell casing with the maximum load of explosive. Tests carried out at Rechlin (where most of the Luftwaffe aircraft and weapons tests were done) showed that with a "M-Shell" with 85 grains of explosive, five hits could destroy a B-17 or B-24 bomber. The second type of shell, the incendiary, was meant to be targeted at the fuel tanks of the enemy plane. Since some penetrating force was still needed to overcome the armor or airframe of the target, and not have the shell break up or explode upon contact, a hydrodynamic fuse was fitted so that the shell only exploded once it came into contact with liquid.
