Good mil-spec trigger - ALG Defense Quality Mil-Spec QMS 5.5lb Trigger

As far as mil-spec triggers go, this is one of the best but it's still just a mil-spec trigger. Don't expect this to be in the same league as the myriad of specialty AR triggers on the market but it's also far cheaper. It's a good choice if you prefer the reliability of a mil-spec trigger to the light, crisp pull of the more expensive options.
