The AR-15 "EBG" (Evil Black Gun) is perhaps the most versatile and modifiable rifle available on the market today. It is known by many of us as the ultimate "switch barrel" rifle. There are more models, variations, configurations, after-market attachments, barrels, triggers, gadgets and gizmos out there for the AR-15 than any other rifle. With the only exception perhaps being the Ruger 10-22.

You can change the entire function of the rifle by simply pulling two pins, removing the upper receiver unit and dropping another one in its place. You can go from a carbine length, open sight, home defense weapon to a 24 inch, heavy-barreled, long range precision Prairie Dog ‘splasher in just a few seconds.

In the following pages we hope to provide you with useful and informative information that will greatly enhance your EBG shooting experience.
