Adam's Review of Faxon Firearms EXOS-513 Pistol Compensator for Glock and FX-19

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
