Adapt. Overcome. The SureFire SFA2-556-1/2-28 is a closed-tine adapter specifically designed and engineered for compatibility with SureFire Blank Firing Adapters or any Mil-Spec BFA used in training evolutions that require a blank firing adapter. Like every SureFire SOCOM adapter, the SFA2-556-1/2-28 also serves as a rock-solid, precision mounting platform for SureFire SOCOM Fast-Attach Suppressors, as well as serving as a standalone muzzle device. It closely represents a traditional birdcage flash hider, with wrench flats for ease of installation. Just like the other SOCOM muzzle devices, this adapter is precision machined from heat-treated stainless steel which is highly resistant to gas and particle erosion. Additionally, it utilizes multiple bearing surfaces to ensure proper suppressor alignment every time.

Great flash hider and suppressor mount. It’s the shortest one they make and looks great on my 10.3”

I really like the OG look and I particularly like how short it is. RC2 locks up just fine works great!

You don’t need Labyrinth seals for your can just buy this for the og look it work
Labyrinth seals work till they don’t why get caught lacking in the aesthetic department when you could look fly like a white cia guy from the Iraq invasion
