First, simmons is not even on your initial list, but since you said 4, I'll take as a given that you meant to include them.
Second, and more important, WHICH Burris(es), WHICH Weaver(s), WHICH Redfield(s), and WHICH Simmons(es). There are mutiple lines within each maker, both old and new, with WILDLY varying levels of quality. Must be more specific please.
