CLEANING THE LOWER RECEIVER
WARNING! Unload the firearm before cleaning. Look
into the ejection port and visually check the chamber

the firearm. Always wear eye protection when handling,
disassembling and reassembling the firearm. Failure to
follow these instructions may cause property damage,
personal injury and/or death.

rearward to inspect the chamber. See Figure
