My wife and I were able to collectively breath a sigh of relief when we made our first visit to The Smoke Pit after moving from Charlotte to Concord. This was the result of determining that we didn't have to make the drive back to Charlotte for good BBQ. At this point we have tried all of their meat variations and most of their sides and conclude that they serve up some delicious stuff. Particularly noteworthy is their pulled pork or pulled chicken, fried okra (one of my wife's all-time favorites), and collard greens. Their portion sizes are so large that we both share a meat and two sides (along with bread) and are both left satisfied.
The only drawbacks of note is their limited seating (due to their justified popularity) and awkward situated line to the register. The door that leads to their outside seating is typically blocked by this line and their waiting area, for picking up food to go, is situated along the wall where the line is standing. All in all not enough to pull this rating to 4 stars.
If you are anywhere around Concord (or passing along I-85), I highly recommend giving them a try.
