Q. What is the best M855 to get?
The name most often tossed around as the best M855 is IMI. Israeli Military Industries are the same people who make Q3131A and their M855 is apparently just as reliable. Additionally, you can find it newly manufactured. Lake City and Winchester both produce M855, but it is almost never available anymore, and certainly not as new-production. The only exception is that Winchester makes M855 available to police departments. Occasionally, small quantities of this gets traded back to ammo dealers, and become available for civilian sales.
