Magpul | Armorer’s Wrench | Black

Magpul's Armorer's Wrench (MAG535) is a single piece of heat‑treated US steel for AR‑15/​M4 work: USGI and pin‑style free‑float barrel nuts, carbine castle nuts (including ASAP end plates), rifle receiver extensions, and a 3/4‑inch flash‑hider wrench. A 1/2‑inch square drive takes a torque wrench, and Magpul stamped the common torque specs on the tool. Two hammer faces, manganese‑phosphate finish, 11.7 inches long. It will not fit larger pistol‑style buffer tubes. Made in the USA.
