Have a Bushmaster AR. Trigger is caca. Anything I can do myself to make it smoother? Best left to a smith? Or am I looking at a new Timney/Jewell/etc? Not looking for match grade performance, just trying to put the fear of God into cans and bottles out to a hundred yards or so.

+1 for (partial) 15 minute trigger job.

Read it to get the general idea. All you are really doing is polishing the engagement surfaces to smooth things out, which does just that. You are not trying to remove any metal depth. And it will make the pull feel a little bit lighter, since it is smoother. I have never bothered to trim the springs to try and really get a lighter pull, as I am concerned about reliability.

So I start out by popping the ceramic rod out of a "V" type knife sharpener for initial polishing use/work. A after running the hard ceramic over all the surfaces for the initial polish, put things back together with a dab of valve lapping compound and cycle the trigger a bunch, reapplying the compound to the engaged surfaces every 10 cycles or so....
