Detailed Specs:

Upper & Lower Receivers

  • F&D Receivers are manufactured to the most specific set of tolerances in the defense industry; F&D utilizes tolerance stack-up engineering software and advanced inspection systems. F&D maintains pride in stating that it unequivocally manufactures the finest  auto-loading rifle components in the world.

Material

  • F&D’s custom-supplied, hand-forged 7075-T652 is the highest strength aluminum alloy available; up to 20% increased tensile strength from non-forged 7075-T6.  Receivers are match pinned for a perfect fit, not too tight or too loose.

Coating

  • Hardcoat Anodized IAW: MIL-A-8625, Type III Class 2

Operation

  • Flawlessly feeds from Magpul P20 magazines
  • 20 MOA tilt on top rail adds scope range
  • Side charging handle, non-reciprocating

Barrel

  • 308 Winchester Match chambered, 5R cut rifled by Bartlien Barrels
  • 1:10 twist; 5/8″-24 threads
  • 18″ length: effective range up to 800 yards
  • 22″ length: effective range up to 1000 yards
  • Sub-MOA accuracy
  • 416 Stainless, more uniform grain and density than mass-produced hammer-forged 4140 & 4150 alloy steels
  • Heat treated, lapped, and polished bore

Assembly

  • F&D’s rail system eliminates the barrel nut, allowing simplified and consistent barrel removal and reinstallation, while providing an extremely rigid connection to the upper receiver. F&D’s exclusive bolt-on interface maintains much higher rigidity than barrel-nut designs, and consolidates the absolute lowest and most compact rail-height available compared to any piston or direct impingement rifle system. This proprietary interface exerts 8200 lbs of axial force against the upper receiver, compared to 6700 lbs with standard barrel nuts utilized on most other AR-10 style rifles. Radial-clamping “quick-change” barrel systems exert little to no axial force against the upper receiver and reduces accuracy consistency. Axial barrel retaining force is one of the most significant structural contributors to accuracy and consistency on AR platform rifles.
