Tapco
The Tapco Tap22060 castle nut is a steel component built for AR platform rifles that require a reliable, no-fuss receiver extension fastener. If you're assembling an AR-15, AR-308, or any direct-impingement rifle using standard receiver tubes, this castle nut handles the critical job of securing your buffer tube to the lower receiver with the strength you need for thousands of rounds downrange. Black anodized finish resists corrosion and blends seamlessly with modern rifle builds.
Castle nuts are one of those parts that work quietly in the background—until you need to change out your stock, adjust your setup, or service your rifle. A quality steel nut like this one won't strip, crack, or round off when you're wrapping it down properly with a castle nut wrench and staking tool. Tapco's steel construction gives you the durability that matters on a parts list where corners shouldn't be cut.
Whether you're building a new AR, doing a stock upgrade, or refreshing your setup after years of use, keeping a solid castle nut on hand makes sense. This is the kind of small-part reliability that keeps your rifle running and lets you focus on what matters: hitting your target.
