Knights Armament KAC Free Float Rifle RAS, Mk12 Mod1 KM-21318

Knight's Armament Long Free Floating "Rifle" RAS, MK12 Mod 1 w/3-ribbed panels

The Knights Armament Free Floating RAS #21318 stands as the definitive rail system of the Mk12 Mod 1 Special Purpose Rifle. This legendary component transformed the SPR program, distinguishing the Mod 1 variant with its distinctive quad-rail profile and unmatched mounting stability. After years of unavailability, KAC has released a limited production run of these iconic rails.

Key Features:

- Precision machined aluminum construction
- Factory new production to original specifications
- NSN: 1005-01-562-0913
- Includes KAC rail panels
- Complete barrel nut and mounting hardware

The RAS mounts directly to the upper receiver using KAC's proprietary barrel nut system, creating a true free-floating installation that enhances the Mk12's legendary accuracy potential. Its adoption by US Navy SEALs and special operations forces cemented its place in military history, while also finding service on the NSWC RECCE Rifle platform.

Technical Specifications:

  • Full-length Picatinny rails on all surfaces
  • Properly indexed for MIL-STD-1913 accessories
  • Correct factory finish matching period production
  • Clone correct markings and specifications
  • Direct-fit compatibility with Mk12 Mod 1 components
  • Includes three KAC 11-rib rail panels
  • Will fit the KAC forward grip as well

For the discerning clone builder, this represents a rare opportunity to acquire a factory-new example of an otherwise obsolete military component. While the Mk12 Mod 1 has passed into legend, Knights Armament's limited production of the #21318 RAS allows collectors and enthusiasts to complete their builds with genuine, clone correct hardware. Each rail ships with complete technical documentation and KAC's proven mounting hardware, ensuring both authenticity and proper installation.

Don't miss this opportunity to secure an essential piece of Special Operations history. The Knights Armament RAS #21318 remains the heart of any authentic Mk12 Mod 1 build, representing the pinnacle of early 21st century precision rifle development.
