Just picked up my Colt LE6920. (Actually it's stamped M4, which is interesting.) It's put together perfectly, and I'm very impressed. One thing, though: the trigger is average at best. I'm probably spoiled by Jewell triggers on bolt actions and nicely done 1911 triggers, but still ... There's enough creep that it feels like a two-stage trigger. Is there anything fairly simple--polishing, springs, magic spells--that can take the trigger to above average?
