Trigger kit - JP Enterprises Reduced Power Trigger Spring Kit For AR-15

I recommend this kit. Dropped about 1 to 1.5 lbs. off trigger pull. Doesn't sound like much but it is. While your there, lightly polish mating surfaces with a dremel cloth attachment in conjunction with polish cream. Don't over due it and don't file or grind metal or you'll ruin the whole thing. Apply good grease and you'll be smiling when done. Oh yeah, you'll have to bob the hammer due to lighter spring or you may get misfires.
