Why would you stuff a combat rifle in your back pack? Oh, excuse me Mr. Ambusher, I need to get my rifle out of my back pack. If it's not in your hands, have you ever heard of a sling? Of course, this from a guy who reccomends an AR-15 slung to a thigh inside the pants. Ouch! Oooh! Owhh! I caught the front sight on my thong! Err, I mean my supporter. God, your fun!
