I'd be interested in hearing some details about how you go about correctly buffering your ARs. Mine shoot pretty soft so I haven't bothered to mess with them, but improvments are always welcome.
Im happy to hear what you have and offer an over the Internet guess as to what might help. But if what you have shoots soft now my first recommendation would be to leave it alone. If you change one thing it can affect others and sometimes you can create more problems than you solve, trying to get it juuuuuuuuust right.
