Description
Multi-Purpose AR-15 Armorer’s Wrench for Barrel Nuts, Castle Nuts and Muzzle Devices
If you build or work on AR-15s, this is the tool you’ll reach for on almost every job. One wrench handles the high-torque steps on both the upper and the lower: barrel nuts, castle nuts, buffer tubes, flash hiders, muzzle brakes and free-float rail installs.
It’s made from heat-treated steel with a black powder coat and weighs about 18 oz, so it has the heft to break loose stubborn parts. Built-in 1/2″ and 1/4″ drive openings let you use a torque wrench when a part calls for a specific torque value, and the ergonomic handle gives you solid leverage.

First time purchasing from 80% lower. The fitment of all the parts is very good. Also customer service was very good as well. Mike and Eric is very helpful with some mix up with UPS. I’m Glad I bought parts from them I will continue to do so.
David Hall –
Performed as expected. It’s got some weight to it, feels well made.
James Elledge –
Good basic wrench… open ended for castle nuts on bigger buffer tubes which Icouldn’t tighten with a more expensive close ended wrench.
Kenneth Ball –
And a great price. Received the item quickly. Will definitely be back for my next purchase.
Rickey Kinzey –
Worked perfectly. It is an excellent product
Brian M. –
Quality built tool. I’ve seen lots of similar tools complained about for slipping or warping under pressure, but this tool is solid built. If it doesn’t work well for you, it’s your technique, not a tool issue. The only con i can think of is that the finish is not durable for a production environment. For me, it will last a lifetime.
James Uccellini –
I haven’t used it yet but it looks good.
