NOS M66 Gun Ring Leg Mount Adapter Plates, Military Vehicle

(1 customer review)


Military surplus, New Old Stock (NOS).

This set of three plates are used to adapt an M66 Gun Ring onto the leg mounting system on M939 series military trucks. (This does *not* include any gun parts, the gun tray, gun ring, mounting legs, or any bolts).

The adapter plates should still be usable on M39, M44 and M809 series trucks, but you might not need all 3 of the plates due to the smaller cab.

    I bought a set with surface rust, the rust was definitely overstated. They hardly have any rust at all, and clearly look NOS. I don’t even need to repaint them. What a great deal on hard to find parts! I was very pleased with every aspect of this purchase and wouldn’t hesitate to buy from Green Iron Road Wear again.
