Good, not great - Lion Gears SG-ML150R M-Lok 5-Position Folding Grip

I would have rated 5 stars, but for me that means that it was absolutely perfect. I would give it 4.5 if it would have let me because the issue isn't major. The problem is the provided screws. Install was as easy as Mlok gets, but when I went to reposition the grip, the hex stripped on both screws. No, I didn't over tighten. I tightened enough for the grip to not jiggle. I love everything else about it. They just need to provide better screws.
