Muzzle Brakes are also known as: Flash Suppressor, Flash Hider, Flash Hinder & Anti Climb Device.

These are designed for LIVE FIRING.

We test all our Muzzle Brakes to be 100% sure that they function shot after shot without any problems.

MFI uses the term "Flash Suppressor" in reference to the shape / look that our Muzzle Brakes have as they are designed to mimic the external appearance of their Military Counterparts.

As many of you know the MOST EFFECTIVE Flash Suppressors in the world are the 3 prong style. The unique harmonics of the 3 prongs cancels out 90% of the flash generated from the muzzle. As our 552 style brake is near identical to the original you will receive the same fantastic performance from ours.

This product fits any weapon with a threaded barrel in 14mm X 1.0 Pitch Left Hand.

Fits Only Original Swiss SIG SANs 552 Weapons Systems.

MFI SIG 552 Style Flash Suppressor is an exact copy to the Original SWISS SIG 552 and is threaded with a 14mm X 1.0 Pitch Left Hand.

As you can see from the photo above... These are exact copies. The photo shows our Prototype in the WHITE / un-coated steel.

The Flash Signature of the MFI 552 Flash Suppressor / Muzzle Brake is identical with the original.

NOTE: As these have uniform flash cuts / venting slots 360 degrees around there is no need for a peel / crush washer.

I just completed a 552 build and reused the original barrel. The parts kit came with a seriously damaged FS so I bought this from MFI and it is nicer than the original. Well worth the money.
