Dewey Brush Adapter Large Converts 12-28 Thread to 8-32 Female Thread Aluminum

The Dewey Brush Adapter doesn't react with ammonia based solvents that attack copper & brass but also leave your patches a blue-green color so you are never sure if your bore is truly clean of copper. Dewey's aircraft grade aluminum has the same hardness of brass, it will not imbed impurities or harm your bore and ammonia will not attack it.NOTE: Size indicates the two ends of the adapter--e.g., "8-32 Female to 12-28 Male" means that one end of the adapter is 8-32 Female (and will accept 8-32 Male) and the other end is 12-28 Male (and will go into 12-28 Female).
