I just KNEW that you'd come up with the goods KtK. There, preserved for posterity.

They started to call this a 'bullet catcher' BFA, similar to the bullet catcher BFA recently(?) designed for the little L85 SA80. A word of advice in respect to this BFA. DON'T TRY IT. It's nothing of the sort. Because instead of just getting the bullet, you'll get the bullet jammed in the choke tube plus the BFA plus the flash eliminator! The saving grace is that you'll get the latter at a much slower speed than the former!
