Frequently the need for a quality pistol muzzle brake has been overlooked by accessories manufacturers. In the past, it required a great deal of hunting and maybe a little cry for help to find a good pistol muzzle brake. That’s no longer the case. The muzzle device specialists at Rex Silentium have come to the rescue with the Razor Tactical Muzzle Brake.

The Most Effective Pistol Muzzle Brake For The Price

The Razor Tactical Muzzle Brake is a compact pistol muzzle brake that won’t unbalance your sidearm with a clunky chunk of metal that doesn’t work. This brake is one of the most effective compact pistol muzzle brakes available today. Its low profile won’t get in the way of sights. The Razor Tactical Muzzle Brake manages recoil and muzzle rise effectively, allowing you to stay on target shot after shot, without having to fight to stay on target and take aim.

Razor Tactical Pistol Muzzle Brakes are available with both SAE and metric mounting threads and multiple calibers. There’s a Razor designed to work with virtually any pistol you choose. Installation is easy, simply apply it to your threaded barrel and lock it in place with the included set screw and wrench.

Competition Legal Pistol Muzzle Brake

The Razor Tactical Muzzle Brake complies with the legal dimensions required by the United States Practical Shooting Association, the International Defensive Pistol Association, and SOF pistol brake guidelines. Finished in Mil-Spec black and machined from quality American Steel, the Razor Tactical Pistol Muzzle Brake is another fine product from the Craftsmen and designers at Rex Silentium.

  • Excellent product- well worth it!

    I rarely write reviews unless I really truly enjoyed the product and this was the case with this muzzle break- not only does it function fantastically but it’s also very visually attractive and nice and sharp should you need it for that function. Threw it on my sub 2k gen 2 with some blue locktight on the muzzle threads and the included set screw, and it has stayed put even after a few range trips. Will definitely order from this company again :)

    I bought this to put on my Sig Sauer 1911 Tacops .45 ACP and can not be happier. I noticed a considerable decrease in felt recoil making follow up shots much easier. The muzzle break is very well made and you can tell the quality machine work that is done by the manufacture. I shoot almost daily and have probably shot 1000 rounds with this installed with 0 malfunctions. In my case no change was needed to the recoil spring or other parts of the gun. I would highly recommend this product.

    treaded on and works fine. I gave it only four stars because the set screw comes undone easily.

    Very good quality for the money and works great on my Sub 2000

  • Great brake with minor flaw

    This brake works flawlessly with CZ Scorpion. Only gripe is with the burrs left behind from machining process that are located on brake’s gas ejection holes.

  • NICE brake

    I purchased one of these for my HiPoint 1095TS 10mm carbine and installed it using LocTite on the single set screw's threads. Needless to say after one firing session with my new carbine the set screw came loose and fell off but the brake held on to the barrel's threads just fine. Now I'm thinking of using LocTite on the barrel threads to hold this brake on firmly. Otherwise no complaints, brake does make a small difference (might be a better one if it were twice as long) and the serrations on the front side ARE very sharp. THANKS Wing Tactical...WBFA.
