Title: AR question?
Post by: CP on September 26, 2016, 05:59:27 AM: How much "wiggle" if any, should there be between the upper and the lower? Every AR that I've handled seems to be a bit loose in this interface. Anything to worry about?

Put a small O-ring around the front lug of the upper; it acts as a spring to keep the joint tight. They are cheap, keep a couple extras for spares because they wear out sooner or later.

I like having the ability of being able to take it down quickly in the field without effort. :dunno:

True with the conventional methods of various shims, allen screws, etc, but not true of the O-ring trick. I agree about wanting to be able to take it down without tools; the O-ring allows you to do that. I also like to install extended takedown pins on my rifles to make this even easier.
