As the FN SCAR was adopted by more units, various end users discovered a need for a longer top Picatinny rail to enable the use of clip-on thermal and night vision devices in conjunction with longer day scopes.  This need would ultimately lead to the adoption of the MK20 SSR. With the adoption of the MK20, the original prototype rails were lost to history, until now.

The Black Hills Designs FN SCAR SSR rail extension allows you to retrofit your existing SCAR to extend the top Picatinny rail.  Recreated from a handful of photos, the Black Hills Designs SSR Rail extension is a faithful reproduction of one of the rarer SCAR parts. Whether you are a cloner or an end user, the Black Hills Designs FN SCAR SSR Rail Extension allows you to position thermals or night vision clip-on devices with 15 Picatinny slots of attachment room.

Installation is simple, quick, and requires minimal tooling. Once installed, the rail extension is part of the SCAR barrel assembly and is ideal for users who want the intended flexibility of their SCAR rifle.
