Tapco TAP22060 Castle Nut Steel Black Anodized AR-15 Platform

The Tapco TAP22060 Castle Nut provides secure buffer tube retention for AR-15 platform rifles with precision-machined steel construction and corrosion-resistant black anodized finish. This essential lower receiver component ensures proper stock assembly alignment and prevents buffer tube loosening during extended firing sessions.

What Makes This Different

Unlike standard aluminum castle nuts that can strip under torque, this steel construction delivers superior thread engagement strength and longevity. The precision machining ensures consistent 1.185-32 TPI threading that matches mil-spec buffer tube extensions perfectly. The black anodized coating provides enhanced corrosion resistance compared to basic parkerized finishes while maintaining the proper torque specifications.

Key Features

• Precision-machined steel construction for maximum durability and thread integrity
• Black anodized finish resists corrosion and provides professional appearance
• Mil-spec 1.185-32 TPI threading ensures proper buffer tube engagement
• Compatible with all AR-15 lower receivers and carbine buffer tubes
• Staking notches allow proper installation with end plate retention
• Heat-treated steel withstands high-round count shooting schedules
• Standard wrench flats accommodate armorer's tools and castle nut wrenches

This castle nut maintains consistent buffer tube alignment under recoil stress, preventing the cycling issues that can occur with loose or worn components. Law enforcement armorers and competitive shooters rely on quality castle nuts to maintain weapon reliability during high-volume training and duty use. The steel construction handles repeated disassembly and reassembly without thread degradation.
