Birchwood Casey 41301 Shotgun Brass Thread Adapter - 8/32 to 5/16-27 Conversion
Birchwood Casey
The KleenBore ACC17 Aluminum Thread Adapter bridges two different cleaning rod standards—letting you use your shotgun cleaning accessories with a rifle-threaded rod, or vice versa. If you maintain both rifle and shotgun platforms, this simple adapter eliminates the need for duplicate jags, brushes, and patch holders. It converts a standard #8-32 rifle thread to accept American Standard Shotgun #5/16-27 threaded components, making your cleaning kit more versatile and economical.
Built from aluminum, the ACC17 is lightweight and won't add bulk to your range bag or cleaning kit. The finger grooves machined into the outside of the adapter make hand-threading smooth and secure—no tools required. Made in the USA, it's a straightforward, reliable solution for shooters who own guns across different gauges and calibers.
Whether you're consolidating cleaning tools or sharing accessories between guns, this thread adapter is a practical addition to any shooter's maintenance setup. It's the kind of small, smart gear that pays dividends when you're breaking down your guns at the range or the bench.
