Description
The SureFire Closed-Tine Flash Hider gives you the look and feel of a traditional A2 birdcage with the engineering that made the SOCOM name what it is. It cuts down on muzzle flash to keep your sight picture clean, and when you're ready to run a can, it turns into a precise mounting platform for SureFire SOCOM Fast-Attach suppressors. That dual-purpose design makes it a smart pick whether you shoot suppressed some days and bare-muzzle on others.
What Sets the Closed-Tine Flash Hider Apart
The closed-tine layout is the key detail here. Unlike open-prong designs, the tines are bridged at the front, so you're far less likely to snag on gear, slings, or brush when you're moving. It also does away with the ring found on some other SureFire hiders, and the tines can serve as a sacrificial baffle that helps extend the life of your suppressor. Compared to the SureFire 3-Prong, this one runs shorter and lighter, which is handy on builds where you're watching length and weight at the muzzle.
Built From Heat-Treated Stainless With a DLC Finish
This unit is CNC-machined from heat-treated stainless steel that stands up to gas and particle erosion, the kind of punishment a muzzle device takes on high-volume days. The DLC coating adds corrosion resistance and makes cleanup easier after long strings of fire. Multiple bearing surfaces are machined in to keep a suppressor aligned true to the bore every time you attach one, and built-in wrench flats mean installation is a straightforward job with the right tool.
Fit and Feel on Your AR
Set up for .223 Rem and 5.56 NATO barrels with standard 1/2-28 threads, it drops onto most AR-15 and M4-pattern rifles without drama. It's proudly made in the USA, and it carries the reputation SureFire earned building gear for hard use. If you want a clean-looking muzzle device that plays nice with a suppressor down the road, this is a dependable choice.

Frequently Asked Questions
Can the Closed-Tine Flash Hider mount a suppressor?
Yes. It doubles as a rock-solid mounting platform for SureFire SOCOM Fast-Attach suppressors while also working as a standalone muzzle device. Multiple bearing surfaces machined into the body keep the suppressor aligned with the bore each time you attach it.
What threads does this flash hider use and will it fit my AR-15?
It comes cut for standard 1/2-28 threads, which is the common pattern for .223 Rem and 5.56 NATO barrels. That makes it a direct fit for most AR-15 and M4-pattern rifles. Just confirm your barrel is threaded 1/2-28 before ordering.
How is the closed-tine design different from an open-prong flash hider?
The tines are bridged at the front rather than left open, which cuts down on snagging when you're moving through brush or working around gear. It also resembles a traditional birdcage in the way it manages flash. The bridged tines can act as a sacrificial baffle that helps protect your suppressor over time.
Does the DLC finish hold up to hard use?
It does. The heat-treated stainless steel resists gas and particle erosion, and the DLC coating adds corrosion protection while making carbon cleanup easier after long range sessions. It's built for the kind of high-volume shooting SureFire designed its SOCOM line around.
