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 1/2 X 28 tpi, but the rear contour is designed specifically to match the profile of the original Swiss SIG SANs 552 and 553 Pistol Barrels.

Fits Original Swiss SIG SANs 553 Weapons Systems. MFI SIG 552 / 553 Style Flash Suppressor is an exact copy to the Original SWISS SIG 552 BUT it is threaded with a 1/2 X 28 tpi Right Hand thread.

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

SIG USA does NOT supply any of their rifles with Flash Suppressors that look like the Original SIG 552 / SIG SAN / SWISS SIG. Even if you could find an original flash suppressor it would be impossible to mount to the SIG USA rifle or pistol without major modification.

Our product can be used on the SIg 553 model pistol as well as other weapons like AR15s (which looks cool by the way). This flash suppressor has 3 slots which is the same as the originals found on the SIG SAN 552

This Flash Suppressor / Muzzle Break WILL allow the use of a standard US / NATO style bayonet (M7, M9 or M11). You do not need a peel washer to index the FS to the correct location. The peel washers always created a problem in terms of looking incorrect.

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.

My SIG 553 should have come with this as I paid $3800.00+... I got the Michael's Machine FS first and was not happy with the look or the finish so I bought the MFI one... Got it a while ago and it really works... no noticeable flash at all unless you shoot in total darkness. Looks exactly like the original too.

Excellent flash supressor!

A few days ago I received the 552-style flash suppressor for the 553. I had really wanted to purchase the 552-style flash suppressor for the 556, but it looks like they will never be made again (sadly), and I figured the one for the 553 would work on my 556 Pistol. It's perfect! Looks absolutely amazing....WAY better than the stock 556 (AR style) flash suppressor. And it handles flash and recoil much better as well. An excellent addition to a 556!
