I bought a Prince50 one, but it broke within the first few minutes of use. In fact, I had just gotten my ACR and I was poking a bullet in the bullet button, trying to figure out how it works and one end of it just snapped off. I was a bit worried when I first handled the bullet button since it seemed to be made of cheap plastic, I guess I was right about it.
I saw a post on Calguns by an online retailer about a bullet button he had designed and was planning on mass producing, but so far, I can only Google up the Prince50 one.
