It works, but it's not great. - Strike Industries Link Hand Stop Kit

It fits on my handguard just fine. I like the options that the three pieces can be installed as you desire for fitting your hand. Personally, I can't get it to feel comfortable with my hand with all three pieces. I will continue to adjust the pieces until it feels comfortable, or I replace it if I can't. I give it three stars because it works, it's just not entirely comfortable for me.
