Works great and shows no signs of loosening up after several hundred rounds of 7.62x39. Just make sure you install it like you’re supposed to; apply a little loctite to the threads, tighten it as much as you can with your fingers and then add another quarter turn using a screwdriver, coin, etc. Good to go!
