    I had a custom rifle, but a stock trigger. I was dealing with it, but knew I wanted a good one. This one caught my eye and I knew the quality of RISE, so I took a chance and ordered it. Very easily installed and I love it. I'm sure there are better, but this is soooo much better than the one that was in there, I'll be happy until the next sale and I get another one.
