Most Helpful Positive Review Works on Aero M5
Just want everyone to know that this works perfectly for M5E1 Enhanced uppers. It's also a high quality tool for a great price.... And here are a few more words to satisfy the optics planet folks... And some more
Most Helpful Negative Review wtf are they thinking
Very upset that they didn’t include this. I did a bit of research and they actually stopped including this to reduce cost. It does not take much innovation to make the barrel nut fit a traditional wrench or just include one. I know for a fact I am not the first and won’t be the last to be excited to...

Geissele barrel nut wrench

by mike s, Verified Owner from CA, United States Written on September 30, 2025
Great price and tool works as intended, can’t go wrong. Mine was a little rusted but nothing a quick scuff and rustoleum couldn’t remedy. A must if you’re installing the geissele handguards.

Best tool for LongShot handguards

by Jerry, from TN, United States Written on May 6, 2025
These are the mfr specified and best tools for proper tightening of the barrel nuts supplied with genuine LongShot handguards. Top level handguards require top level tools....and these meet their standards. Fast shipping, too.
Pros:
  • Won't damage the LongShot barrel nut.
Cons:
  • None
Best Used for:
  • LongShot modular handguards
Would recommend: Yes

Pros:
  • Inexpensive, simple
Cons:
  • None
Best Used for:
  • Castle nut install & removal AR15
Would recommend: Yes

works every time

by matt, from ME, United States Written on February 1, 2025
You need this tool guys. No wrench: no rail. The wrench is something you should always keep in your took box for friends builds and to remind you to build another upper with a Geissele rail.

Grab them when you can

by Idontknowwhatimdoing, from AL, United States Written on December 17, 2024
When Geissele runs out and you need one it's not going to be easily found. Regardless they have an amazing multi point locking system within the handguard
Pros:
  • Having one
Cons:
  • Proprietary, a regular barrel wrench can possibly get it done id rather know it's done right
Best Used for:
  • Geissele barrel nut
Would recommend: Yes
