I think I'm the kind of person who would rather do it myself than buy anything. So I've been wondering if this would work for some time now, I finally tried it. My goal was to reduce the takeup time and over travel on a standard AR trigger...Here are my results:
I took a DPMS lower that's been sitting for some time now and went to town.
I picked up the following items, total price was like 6 bucks I think,
6x34 tap
no32 drillbit
2 6x34 set screws
blue loc-tite
Here's the sequence of events..
Step 1: The dogs and I went out to the garage and gathered all the parts I thought I would need:
Step 2: I mounted the lower in the drill press vice, and drilled two holes. The rear most hole is centered around 10mm to the rear of the trigger cutout, the front hole is centered about 5mm to the front.
Step 3: I then tapped the two holes with the 6x34 tap. Cleaned them up and started test fitting the screws.
Step 4: Here the screws are mounted and loc-tite'd in the lower exactly where I wanted them.
Step 5: The lower complete. Assembled with trigger parts for testing. Works like a champ in my hands, time for a range test.
In all I'd say that I reduced the trigger travel by over half. The actual trigger pull, weight, remains the same; in the 7-8 pound range. I'm going to take it out and give it a whirl sometime today probably, I'll inform the results then.
Thanks for looking
