Yea, this detent might work well with a agitaiting or gravity fed hopper, but it will not work at all with a halo. it doulbe feeds like crazy. why would somebody make a product that can only be made for a certain type of hoppers. if you going to make a detent, should it work with halos and everything else? what is teh reason for not making it work with the most populat hopper ever created. thats just rediculous. however it looks great, and re buildable....those are the only pluses.
This detent really doesnt do much. unless you use a revy dont get it. get a ball detent, you will be happier.
