If you decide not to invest, PM me. I have some carriers left over from converting my Sidekick to the Ben Hubbard plug. The Metrics Unlimited plug is cheaper than the others and is still a really good plug. I highly recommend getting one of the new plugs since they cut out the fouling that goes onto the face of the receiver and into the action. One of my friends had to send his rifle back to the factory to have the firing pin replaced. This was on a Huntsman clone by some company whose name escapes me at this time.
