"fluff & buff" Ar15 trigger?

    Well after pulling the trigger on Zak Smith's sweet AR-15 at the Colorado THR Get-together I realised how much I hate the stock trigger on my RRA AR-15.

    However I don't have $200 to buy one of those cool aftermarket trigger groups like that nice new Chip McCormick one (and I want a single stage trigger, not a 2 stage).

    So if I get the old *gasp* Dremmel out and put the buffing bit on it is there any way I can improve the stock trigger on my AR?

    I could spend up to $100 to improve the trigger (but I'd rather not).

    I had modded the sear and hammer of my plinker using a Dremel-type tool (actually the early Craftsman model that was private manufactured for Sears by Dremel). Previously, my other ARs had competition triggers in them and wanted to see what I could do with a stock base AR parts.

    Smoothed and reduced the sear notch on the hammer a little, polished the bearing surfaces, and did the spring trick which I found out about at AR15.com. (Discussed in the link provided by yy.)

    One thing to do to help with pull weight not mentioned is to make sure the bearing surfaces between the sear and sear notch are square/flat with respect to the center of the pivot point of the hammer. My plinker, a DPMS Lo-Pro Classic, had a slight angle in the notch that caused the hammer, when the trigger was squeezed back, to be further drawn back slightly past its already cocked position. This raised pull weight due to the friction in the angle notch and winding the hammer spring further when squeezing the trigger. Square it up and this goes away.

    Pull weight went from 6.5-7# to 3.5#.

    Be sure to go slowly and take your time. I must have taking out/put back in the trigger a dozen times until I was satisfied. Going to far could get you unintentional discharge, full auto (uncontrollable), or bursts.

    I took emery cloth and wet oil polished my bushmaster trigger group with moly lube.

    If you will go over the parts a couple of times the result is amazing and the moly kit only costs about $20. The manual effort is higher but the results are worth it.

    I discovered the stuff a couple of years ago and all of my rifles and pistols have been treated with it. If you shoot a lot you should repeat the treatment once in a while.

    I installed the JP Reduced Power Springs from Brownells, with a slight polish on the engagement surfaces, the difference is amazing!
