The Brownells AR-15/M16 Receiver Taps & Dies chase and clean the two most important threads on AR-15/M16 receivers—the 1.250″-18 tpi corrects out of spec or cross-threaded upper receivers and barrel nuts, while the 1-3/16″-16 tpi makes receiver extension (recoil buffer) tube and lower receiver threads uniform for easier installation. Manufactured from high-speed steel with plug taps and 2½” (6.3cm) diameter dies, this precision gunsmithing tool ensures proper fitment and function throughout your rifle build or maintenance work.
Whether you’re building a custom AR-15, correcting factory thread inconsistencies, or performing routine gunsmithing maintenance, this Brownells die set delivers the reliability expected from a premium manufacturer. The dies are engineered for durability using high-speed steel construction, making them suitable for both professional gunsmiths and dedicated hobbyists. Clean, chased threads result in accurate assembly and reliable performance.
