I have been running a Halo B on mine for a good two years. It works well once you set your detents correctly. I had to turn in my front dent (I have a center feed 2K Blazer) less than a quarter turn to reduce double feeding.
Hit too often by my teammates
Life's journey is not to arrive at the grave safely in a well-preserved body, but rather to skid in sideways, totally worn out, shouting, "Boo yah! What a ride!"
