Surefire 4 Prong SOCOM Flash Hider

This item is used. It has 200 rounds through it with a suppressor attached. We have cleaned most of the carbon off of it.
 
This flash hider is Nato Stock Number (NSN) marked: 1005-01-599-7048 and therefore is an exact match for your clone build. 
 
While the device is used, it does come with a brand new set of surefire shims along with original packaging, rockset, and the installation instructions. 

Manufacturers Notes:
The FH556RC-1/2-28 flash hider for 5.56 mm weapon platforms is the exact flash hider that SureFire developed to dominate the most rigorous suppressor trial in military history and earn the USSOCOM suppressor contract. Its four-tine design significantly reduces muzzle flash — typically greater than 99% compared to a bare muzzle — delivering extreme signature reduction and rugged dependability. With multiple bearing surfaces that ensure proper suppressor alignment, the FH556RC-1/2-28 serves as a rock-solid mounting platform for any SureFire SOCOM Fast-Attach® suppressor or Surefire Warden Device.
