I am looking to buy a complete upper. I have a Wilson Combat Super Sniper that has a heavy barrel. Instead of selling this gun I want to buy a complete upper to put on this bottom for everyday use. The gun is to heavy to use as a grab and go tool. I would like to know what the general population believes would be the perfect upper for the situation I have described. I have always like optics ready ar's but, the grab and go may need fixed open sights. OH btw, I figured this would be a great topic to take your mind off of the problems at hand. I wish the best to all that are dealing with the issues many of us are facing.
