I usually hand-select my lower-to-upper fit from batches, so that I get a really tight gun. I don't like Accu-Wedges, since they increase the tension of the receivers away from each other, rather than towards. I have also gotten good initial results with Cerakote, since it adds surface thickness, but the guns will eventually shoot loose if you shoot alot, and use a lot of sling tension.
