a lot of guys with ccm lo-rise feed knecks have standard feed knecks with nasty looking vicegrip marks in the bottom of their kit bags.
Just grab it with ye olde vice grips and wrench it off! Then place it in the bottom of your kit bag and never look at it again!
CCM lo-rises are the nutz, but beware about overtightening them with a halo because they can crack the feed knecks.
