Just wondering if You have any spares laying around that I could pick up or if you know any more info on when they will be available. On a side note, my centerfeed module has threads on both sides for a ball detent, one has part of the feed neck on the inside, so the detent will not thread all the way in. Is there a reason for this? Is the ACE going to use this some how? Could that part of the feed neck be drilled out so that the detent could go in either side of the module?
