I had two interesting rifles come into my shop today. They were both M16A2’s with BALIMOY MFG CO. lower receivers. From my limited research on the web, the receivers were made as M16A1 replacement receivers for Anniston Army Depot. The two that came into my shop were then converted to A2’s at some point. You can see form the pictures that the number one from the A1 was removed and the number two stamped in its place. Also the AUTO was milled out and BURST was stamped in next to the selector switch.

The reason they were in my shop is also very interesting. The two rifles have duplicate serial numbers with two other M16A2 somewhere in the Army. I had to stamp an A at the end of the serial numbers to differentiate them
