These are the ebay/amazon knockoffs of the DAA Racemaster. Work really well, but not quite my style for social run and gun range outings. Show some light use, but no stripped threads, broken parts, or abuse. Each one has three different inside inserts, two back inserts, and can be oriented bullets forward (rightie), bullets forward (leftie), or bullets out. Also included are six DAA single stack adapter plates. $90 shipped for the set.
