I bought a handguard from a local co. and they provided a barrel nut that has 4 slots spaced at 90*. My magpul AR-15 wrench won’t work. Will this? Manufacturer Answer

This would depend on your what kind of barrel nut your local company is using. I would encourage you to reach out to this local company and see what tool they intend for use with their handguard to ensure it is not a proprietary tool. If it requires a standard AR15 Carbine Stock Wrench, this tool would most likely work, depending on the tolerances they hold on their barrel nuts.

Helpful Positive Review Great Wrench by T, Verified Owner, September 13, 2021
Works well on an application that has very tight tolerance between the muzzle device and the handguard. It is made from quality metal that should not chip or break away. Fits a torque wrench well and small enough to not get clunky when you are torqui...

Most Recent Reviews Griffin wrench great for low clearance by Gunner V. Fox, Verified Owner, July 8, 2025
Wrench flats are great to have, but they are not always accessible for a few reasons. If you have to install your muzzle device AFTER you install your rail, and there is not much gap between your rail of choice and the device, then getting a wrench o...
