Easy install with great results - RISE Armament RA-100 AR-10/15 Two-Stage Trigger

I replaced a milspec trigger. This 2 stage trigger is way better. Much smoother and a far better glass break if you will. I didn't measure weight but it was much less. The install took about 20 minutes. I'm not a pro. I forgot to keep the trigger spring legs on top of hammer pins. The legs fall into the grooves of the hammer pins to stop walkout. From left side of rifle,groves on pins, go in last.At least on mine.
