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...

This does not come with the Geissele rail systems when you order them you have to purchase this secondary. But it does what it's supposed to do, works great.

I guess i needed it

by Joshua, Verified Owner from GA, United States Written on May 26, 2026

Had to purchase in order to install G$ handguard. Guess it wouldn’t have been ideal to include in the package for the price. Works as intended.

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.
