My husband thinks I need a new gun for squirrel hunting. His friend from the military says an AR-15 .223 would be great for me. I like everything about the gun but am afraid that it will be unsafe in my hunting group of 8-10 people. Most of the kids have never shot before and we all circle the tree looking for the best shot w/ 2 dogs running around. Does anyone know if this gun will be safe for this kind of crazy, some times unpradictable group? If not, any suggestions on a similar .223?
