Help a poor guy out, can someone point me to that thread? Dan C |
Did you happen to lighten up the hammer when you cut the spring? I was having light strikes as well before I cut a bunch of weight off the "tail" of the hammer... By removing the weight it allows the weakened spring to accelerate it better. Doing this got the primer strikes just fine again and I've had 100% ignition except for a bad Wolf round that didn't go off no matter how many times I hit it.... see Here for pics... they're big. Edit: Here's the link for the 15-minute trigger job |

I have done the trigger job on an Oly lower kit. I did also bob the hammer quite a bit. I have only about `500 rounds through it, but have had no FTF to date. The Oly lowers seem to be a bit light to begin with, but it works well. I am planning to do the same mod on a lower that I have a Rock River kit in. I'm hoping that it will lighten the RR trigger, because it seems pretty heavy to me. Before I tried this, I purchased several hammer and trigger springs from Midway so I would have them, just in case. Haven't needed them yet. For what it's worth............ |

I tried the 15 min. trigger job for the first time. I am very happy with how much smoother the trigger operates. But the trigger pull went down by about one pound. It started out 8.5 to 9 lbs. and now runs 7.5 to 8.0. Is this what most people experience. I was hoping for a little lighter. But like I said very smooth. It is my first build and I am trying to learn the tricks. Thanks... |

I tried cutting the springs etc. but didn't like the results so got a set of JP Enterprises springs and they seem much better. The change that really made a difference and and allowed me to adjust both the pull and take up was a homemade version of the Long Range Products AR-15 trigger adjuster. Brownells sells this adjuster for about $44.00 but it is just a grip screw drilled and tapped for an internal screw that contacts the rear of the trigger. The picture in Brownells tells it all, easy to make with basic tools but does require fitting and knowledge of how the trigger works. Dave |
Buy a new part when you can just tweak the one you have in hand????? My God man, where do you every come up with these idea's? 
|
J. P. Enterprises Reduced Power Spring Kit for $10 OR Yellow Tavern Reduced Power Action Kit for $4. |
|
The Yellow Tavern spring set works well. I just finished putting 300 rounds through my AR with a cheap trigger job. I trimmed the hammer spur off first. Then used a 1/4" 28 x .500" set screw to reduce the sear engagement. I polished the engagement surfaces with a Cratex wheel. The total cost was less than $3.00. I now have a crisp trigger pull of 3 lbs. with minimal take up. Can't see any reason to purchase one the high dollar triggers. |
