Three thread standards exist in gun cleaning: 5-40 for .17 and .20 caliber, 8-32 for .22 caliber and up, and 5/16-27 for shotguns. This 2-piece brass cleaning rod adapter set bridges all three - so one cleaning rod works with every brush, jag, mop, and slotted tip you own, regardless of caliber or gauge. The set includes a 5/16-27 to 8-32 adapter for shotgun-to-rifle conversion and an 8-32 to 5-40 adapter for standard-to-small-caliber conversion.
Most gun owners accumulate firearms across caliber classes over time - a .22 plinker, a .308 deer rifle, a 9mm carry pistol, a 12 gauge shotgun, maybe a .17 HMR for varmints. Each one technically needs different cleaning rod threading. Instead of buying three separate rods and triplicate accessory sets, two small brass adapters make your existing rod universal. That saves money, kit space, and the headache of sorting through mismatched threading at the cleaning bench.
Solid brass on both adapters - the same material used in quality cleaning rod accessories. Won't corrode from gun cleaning solvents, won't strip or damage the threads on your rod or attachments. Toss both in your kit and never worry about thread compatibility again.
