Most Helpful Positive Review Excellent Wrench
Purchased this specifically to install a handguard from a tactical company in Texas. My other wrenches wouldn’t work, because the “pins” that engage the fas tube holes weren’t long enough. Since PRI used a similar attachment system, this tool worked perfectly.
Most Helpful Negative Review Looks is deceiving
Doesn't go into barrel nut without hammering into it, save your money. I'm very disappointed because Da Pic looks AWESOME, but again it's not worth it. Doesn't work well, garbage item, don't buy, what else you want me to say? No Stars!

Long studs

by Gunner257, Verified Owner from SD, United States Written on August 18, 2026
This wrench has studs that project further out than most. This makes it better for the installation of LaRue handguards, or any other handguards that have a barrel nut with recessed milspec-type holes.

Junk, poor craftsmanship

by Anthony Day, Verified Owner from OH, United States Written on June 8, 2026
The pins are flared at the end and would require grinding to get the edges rounded to fit in holes of the barrel nut. Who wants buy a product that promises a certain job but then you have to fashion the tool to even work? Poor craftsmanship and poor oversight.
Pros:
  • None
Cons:
  • Poor craftmanship
Would recommend: No

Using a torque wrench makes it easier, but it does what it says it does.

Very strong wrench - have gone up to 80 ft-lb no problem

by Slu54, Verified Owner from OR, United States Written on July 13, 2025
Great for standard AR15 barrel nuts or nuts for PRI handguards. Very strong have taken on and off barrel nuts up to 80 ft-lbs with 3 ft breakers and there's 0 sign of deformation or fatigue. Of course since this has 5 engagement points it has to be able to fit on over your barrel, so mostly likely you will need to remove muzzle device and gas block to use.
Pros:
  • Strong
Cons:
  • disassembly needed
Would recommend: Yes

Right Tool For An Overtorqued Barrel Nut

by Grey Beard, Verified Owner from NH, United States Written on March 1, 2024
It was time to change a barrel on one of my service rifles before the shooting season starts. This was the original barrel on this upper, with 3,800 rounds through it. The barrel nut tool I had from another barrel job worked well last time. It’s a half circle shape, with nubs to engage the slots on the barrel nut. But not this time, the nut was torqued well over 70 lbs before it slipped and sheared off 2 of the teeth. Serched the web, found this product. Went to their website like what I saw and purchased it here. I also bought a new barrel nut. The old barrel nut came off with no problem. Torqued the new nut to 45 lbs. the fingers on this tool completely engage the nut 360 degrees. This is only for barrel nuts, no bottle openers, or extra features. A superior tool made in USA.

Excellent Tool

by Anonymous, Verified Owner from MO, United States Written on July 15, 2021
Multi-use AR tools usually include a feature to remove a USGI barrel nut. These can work fine . . . if the nut was not over-torqued at the factory. This tool is sufficient for the job. It is a must for installing a USGI barrel nut to spec. The ability to use either size torque wrench is great. Quality is beyond sufficient.

Good for d-ring nuts

by Doug, Verified Owner from OH, United States Written on September 26, 2020
Bought for what may be the only time I'll ever use it. Happy about the quality for the price. Fits nice and tight. Very heavily made and sturdy.

Highly recommend for those that don't want to spend a fortune on a tool that gets used once, or once in a great while.
Pros:
  • solid construction
  • Tight fit
  • Not expensive
Cons:
  • Not cut open for placement. Requires running all the way down the barrel.
Would recommend: Yes
