Rex Silentium has introduced a new muzzle brake designed for pistols and pistol caliber carbines. The new brake is called GunFighter. It is full auto rated meaning that it should function flawlessly even in the most intensive firing sessions.

Large ports of the GunFighter muzzle device are designed to provide a maximum amount of recoil reduction and muzzle rise compensation. The first slot is pointed upward and works as a muzzle rise compensator. The following two ports are designed to redirect the gasses to the sides and upwards thus mitigating the felt recoil and also aiding the muzzle flip compensation. The flat profile of the brake won’t let it interfere with the iron sights of handguns.

Here is how the manufacturer describes this muzzle device:

The GunFighter Pistol Muzzle Brake was built for aggressive recoil and muzzle rise reduction. The GunFighter brings control not only to your pistol but to your pistol caliber carbines (PCC) too. Ruthlessly tested on a submachine gun, the Gunfighter enhances shot to shot accuracy. Rather than full auto bursts spraying at a target you now have control and much tighter grouping

The Rex Silentium Gunfighter muzzle brake comes with a lock nut and does not require a use of washers, set screws or thread locking compounds to install it. Basically, all you need to install it is to thread the brake onto the barrel, align it properly and tighten the lock nut thus fixing it in place.

The GunFighter brake is made of steel and features a mil-spec black nitride finish. It has an overall length of 1.88″, a width of 1.15″ and the thickness of this brake is .80″. The GunFighter muzzle brake weighs 2.5 oz. According to the manufacturer, the dimensions of the brake make it compatible with USPSA and IDPA rules.

Here is also an important notice quoted from the company’s website:

Please note that due to the effectiveness of our brakes it is recommended that you use a lower spring rate (or spring force) on your pistol’s recoil (or main) spring. Lower spring force springs are available at and other venues. See you local gunsmith for proper installation.

The Rex Silentium GunFighter muzzle brake is available in one of the following thread pitches and caliber options: 1/2-28 (9mm, .357 caliber), 9/16-24 (10mm, .40 caliber) and .578-28 (.45 caliber). The MSRP for these muzzle brakes is $79.99 regardless of the caliber and thread pitch choice. Right now the brakes are available at a discounted price of $59.5. The prices also include the free shipping throughout the USA regardless of the ordered quantity.

    Since most PCCs I'm aware of have a 1/2 x 36 thread pitch I think they are missing their target. Pun intended. :)

    The mounting system is unusual, and seems really long, especially on a pistol.

    Otoh, I have a relative with low hand strength, and I've considered experimenting with a braked pistol just to see how much lighter the recoil spring would be. Plus, a hammer fired gun instead of striker. For example, a Beretta 92 has a 13 pound recoil spring by default, so a brake would probably bring that down to 11 or 12.
