  1. If a better option is available, avoid this one

    First of all, I actually bought this same wrench from a local shop. DPMS brand. I only needed it for one thing, the castle nut.

    Long story short, the castle nut pin is so short and poor quality that it just slips up and will eventually turn itself into more of a bump. The curve also doesn't fit the castle nut quite right, which may have also helped with some of the slippage.

    Conclusion: Buy a dif wrench for anything castle nut related

CA$39.67

This specialized tool is designed to perform important screwing jobs when working on your AR-15. (full list at the bottom of this page) Plus the heavy end has a flat area to use as a hammer, convincer, or thumb detector.

(If you don't need to work with barrel nuts, you might get away with using our Basic AR-15 Wrench)

There is a square hole for a 1/2" torque wrench (not included) to get the perfect amount of torque on your barrel nut (though many people use a calibrated wrist).

We also sell barrel nut grease to prevent thread seizing.
