Most Helpful Positive Review How to have a flat shooting pew!
Easy install, red loctite isnt any worse than rocksett. When cycling its very flat, with that being said its pretty typical for lighter ammo to struggle to cycle, most comped 9mm like heavier 124-147gr. But i knew that coming into this and threw the comp on a pistol i dont solely rely on. But with a...

Most Helpful Negative Review Red loctite?
The second I read "red loctite" on the instructions my hopes were dashed. I'm not putting red loctite on a gun. Period. And, apparently, this needs it. It constantly works loose destroying the accuracy. The comp pulls the barrel out of line just enough to where a I can no longer run any flat, or h...

I installed this on my Ruger RXM and I love it!

by Adam, Verified Owner from WI, United States Written on July 26, 2025
I installed this on a matching Faxon barrel into my Ruger RXM. It shot crazy flat. I did install a lighter recoil spring prior to the Comp/Barrel combo. This caused failures to achieve battery. I reinstalled the factory guide rod and it ran great. Super flat shooting. I ran Winchester white box 115gr through it and noticed some jacket/lead transfer on the compensator. Choose your ammo wisely.
Pros:
  • flat shooting
Cons:
  • Loud
Would recommend: Yes

faxon exos-513

by t, Verified Owner from WV, United States Written on May 31, 2024
Got one for my sw2 palmetto state dagger slide and one for sw6. Fits great and does not affect my ammo choice. I like that it doesn’t attach to the guide rod, but has tightening set screws. Looks great on my daggers

faxon exos

by Emerica138ost, Verified Owner from MA, United States Written on December 28, 2023
Faxon has really out done themselves. This is a great product and perfect price point as well. I bout the gen 3 g17 comp and man does it make a difference. My groupings have improved obv with the help of this flattening comp and of course practice. Great quality and craftsmanship item here must buy.
