As a new owner of an AR-15 in January, I was looking for information about them (ammo, scopes, cleaning it, break-in time, accessories, etc.), and I found this site. I have found everyone who uses this site to be very informative helpful to all especially to us new guys. It is great to find a group of people willing to pass along their expertise and experiences to others so they can become better at a sport that they love. I can't individually name those that I have gotten information from from reading the postings, so here is a hearty thank you to all that have asnwered other peoples questions. I hope to be able to help you and also help other new guys in seeing how fun it is to own and shoot the AR-15.
