The Birchwood Casey Torque Wrench Set (brand part no. TRQW) gives an AR-15 builder a precise way to torque castle nuts, barrel nuts, and other hardware instead of guessing at hand-tight. Made by Birchwood Casey, it includes a torque wrench with magnetic driver bit retention, a multi-piece bit set covering flat blade, Torx, and hex profiles, and a hard polymer storage case. A distinct audible and tactile click at the set torque takes the guesswork out of hardware installation.

• The included multi-piece bit set covers flat blade, Torx, and hex profiles for the hardware you’ll actually encounter.

Frequently Asked Questions

Why does torque matter for a castle nut or barrel nut instead of just tightening by feel? Under- or over-torquing can lead to a loose stock tube or a barrel nut that doesn’t seat correctly against the barrel extension, so hitting the actual spec matters.

Does the click let me know when to stop without watching a gauge? Yes, the wrench gives a distinct audible and tactile click right at the set torque value.
