Your AM15 UPPER RECEIVER will allow you to easily convert your M16 registered lower receiver into the same functionality of an American 180 .22LR machine gun. Before you install the AM15 on your M16 lower receiver and attempt to fire the AM15, please read all of these Installation Instructions and also read the Operating Instructions.

For ease of reading, the Assembly Procedure is divided into 4 sections:

1. AM15 ASSEMBLY OVERVIEW
2. AM15 BUFFER ASSEMBLY INSTALLATION
3. AM15 FIRE CONTROL ASSEMBLY AND OPERATION
4. AM15 UPPER RECEIVER ASSEMBLY

After completing all four sections, your AM15 will be functional and ready to fire. However, before shooting your AM15, refer to and follow the AM15 OPERATING PROCEDURES.
