Best used with a surefire sound suppressor - SureFire SOCOM 3-Prong 7.62mm Flash Hider Suppressor Adapter

I have a couple of Surefire suppressors so I have more than a few Surefire flash suppressors.

Pros:

If you have a Surefire suppressor the Surefire flash suppressors are the only way to attach the (sound) suppressor to the firearm. I suspect Surefire might do a hub mount version at some point but who knows?

They do a very good job of suppressing muzzle flash when used as a stand alone device.

Cons:

When used without a sound suppressor you will hear a ping noise after each round fired.

They are not cheap.

Timing can be a bit of a pain the first time or two you attach one.

You will need a Surefire tool to mount these or you will likely need to grind a wrench down some in order to get it to fit (for the first closed tine flash suppressor I installed I bought a crows foot and thinned it down a bit, this allowed me to use a torque wrench).

It does need to be timed and unlike an A2 flash suppressor when used with a crush washer, you will need to be within torque specs.

General information:

If you have a Surefire sound suppressor chambered in 7.62 in addition to using it on a 30 caliber rifle you will also be able to use the same suppressor on an AR15 which has a Surefire flash suppressor in 1/2x28 but not the reverse (a 5.56 sound suppressor will not seat on a 5/8x24 (7.62) flash suppressor…which is a good thing).

While the installation appears intimidating at first as long as you have the right tools it isn’t that bad and Surefire has how to videos on line.

Summary:

Unless you have a Surefire sound suppressor or you are looking to do a specific clone correct build (which generally involves the 4 prong 1/2x28) there are other flash suppressors that work about as well for less money and are easier to install. If you have or plan to get a Surefire sound suppressor then this (or another Surefire variant) are the only game in town.
