Most Helpful Positive Review Great Upper with one Caveat
We all know this is a great upper and it is. The main issue is that they are using red loctite on the muzzle break. Even with map gas and yanking on it it took forever to get off and the handguard took some nicks. Not sure whose idea this was but I was shocked they would use red loctite on a muzzle device

by CHAZZLE DAZZLE, Verified Owner from SC, United States Written on July 13, 2025
Geissele is one of my favorite gun manufacturers. I am a fan of the 11.5in, but any size Geissele is gonna be excellent.
Optics Planet is the best when it comes to firearms and firearms parts, and tactical gear.

  • Shooting and CQB
