## For Semi-Auto Parts Kits Click Here ##

I am offering complete (less barrel) Browning M3 Machinegun Kits (less right sideplate). Most of these parts are from carefully disassembled Browning M3-Basic guns. The M3 is a modified/improved M2, modified in order to achieve and sustain a much higher rate of fire than M2 ground or aircraft guns. The M3 can be built as a semi-auto identically to the M2. These kits consist of parts offered individually at For pictures of the parts in these kits, please visit that page.

** Visit for a description of the M3 vs. M2 **
