This manual provides instructions on the operation and maintenance of the Barrett model
M468 rifle. Read and understand it carefully before you try to use your rifle. Your
safety, and that of those around you, depends on your knowledge of your rifle and on your
knowledge of safety rules common to all firearms. Please study the common-sense safety

Sustained rate of fire should never be exceeded except under circumstances of extreme
