The SureFire SOCOM556-SB2 in Dark Earth is a 5.56mm (.223 caliber) Fast-Attach suppressor built for short-barrel rifles. SureFire designed it as the short-barrel companion to the USSOCOM trial-winning SOCOM556-RC, with a larger bore diameter and an internal layout aimed at very low back pressure. It measures 6.4 inches long and 1.5 inches in diameter, and the Dark Earth Cerakote finish suits earth-toned rifle builds. For a short AR that needs a can matched to a barrel of 10 inches or less, this is the SureFire made for that job.

Frequently Asked Questions

Does the Dark Earth model differ from the black one? SureFire lists the SOCOM556-SB2 in black and Dark Earth with the same specifications, so only the finish color changes.

Do I need ATF approval to buy this? No. As of October 9, 2026, ATF no longer requires Form 4 approval, registration or a tax stamp for suppressors. It transfers on a Form 4473 with a background check through a Class 3 (SOT) dealer. State and local laws still apply.
