Reviews & Ratings for FM Products Foxtrot Mike 9mm Muzzle Brake CA Compliant — 2 reviews — Page 1

I bought this to just meet the bare minimum requirements for California's featureless build standards. For CA, when building featureless, I cannot have a flash-suppressor so I had to remove the "Birdcage" from my 9mm Rock River Arms upper and instead install either a muzzle brake or a thread protector. Finding a muzzle brake for a 9mm AR build is hard enough, because honestly who needs a muzzle brake on a 9mm (or any PCC AR build really), and finding one for an attractive price is even harder. I think I paid something like $8 for this muzzle brake so for sure I am satisfied with what I received for the price. However, make no mistake, this muzzle brake is not attractive. The melonite finish seems to have been very poorly rinsed after coming out of the chemical bath. There is a powdery yellow tint on the break surface in general. People looking for ways to make their rifle beautiful will not appreciate that. On the other hand the machining of the part is very well done and this muzzle break will absolutely perform according to what it was designed to accomplish. Further, mine did include a crush washer. I was delighted by that because the listing declared one would not be included. The break I received did not index perfectly onto my barrel, which is not the fault of whoever made this break, so I've ordered a set of shims to be able to complete the installation.

Used this muzzle brake on the FM 16-inch UltraLite barrel and it keeps the barrel shooting nice and flat with minimum muzzle rise & the fit-and-finish matches the FM Barrel nicely as far as recoil reduction it doesn't really help that much but there's no recoil on a 9 anyways
