You know where you can buy a gauge with the legs on it ?
You can pay hundreds for a Starrett or Mitutoyo, but Enco has Chinese knockoffs for a whole lot less money. Accurate enough to take to gun shows or stores to measure guns you are considering. With a 3-1/4" reach, also useful for measuring choke constrictions and tapers. Enco also has a house brand (also Chinese) that is much better quality than their low-end unit, and this one is good enough for the work bench, but I don't remember the brand name.
