Buckster, bear in mind, the tighter the fit between upper and lower the more difficult to pin / unpin the upper to the lower. To facilitate field "emergancies" and because of multi-vendor manufacturing and manufacturing tolerences, there has to be a little slack in the build. Otherwise some parts would not be mate-able without a great deal of trouble. If you spent a lot of time in the field with an AR / MSR, would you like to have to carry a hammer and a punch to seperate the upper from the lower, just in case?
The Accu-wedge is a very viable solution to firm up that interface. Some of us ( myself included ) drill and tap the lower and install a snubber to take some ( but not all ) of that slack and wiggle out. There is another currently active thread about that.
