Warning! Avoid over-tightening to prevent snapping the barrel threads.
The M*CARBO Smith and Wesson M&P FPC Muzzle Brake (10mm Only) not only maximizes recoil reduction and compensation but also extends the firearm by approximately 1" after accounting for the thread length. Suitable for competition or home defense use.
Installation requires a standard AR-15 armorers tool or a 13/16" wrench. To prevent scratches, consider adding 1 or 2 layers of masking tape to the brake.

This muzzle brake combines the advantages of both a muzzle brake and a compensator, allowing for more stable and controllable rapid fire, keeping you on target consistently.
For optimal performance, while Rocksett is not mandatory, it is recommended due to its 1,500-degree temperature rating and removable strength properties. M*CARBO excels in producing high-quality aftermarket parts, enhancing the Smith and Wesson M&P FPC's performance.

Outstanding Muzzle Break!
Installed this muzzle break on my 10mm S&W M&P FPC. Went to the range yesterday and shoulder fired from a standing position with the Holosun HS510C GR reflex sight, no magnification, and no sling. Zero misses on a 6” AR500 steel plate at 100 yards, even with a fast-firing sequence. The 10mm caliber is effective at that distance with the 180-grain bullet and muzzle velocity of 1200+ FPS, and the muzzle break helped with target reacquisition time, particularly during fast fire.

While tightening the brake (with or without the crush washer) I am unable to orient the device to keep it straight....flat side on bottom. Do you recommend shims? Why would this be an issue?
I just ordered the threaded barrel from Springfield for my XDM 10mm. Will this fit it?
No - The threading is not the same.
Will this fit the RUGER 10mm LC Carbine?
We have a 10mm muzzle brake listed on the Ruger LC Carbine Page.
will this work on the 40 cal fpc rifle
Yes - this will fit the .40 cal
What is the size and thread count? (e.g. 1/2"x24, 5/8"x24, 5/8"x28, etc.)
