The World’s Most Advanced Tactical Rifle
Through innovation and design, F&D has created one of the best performing AR10’s in the world, the FD308. The FD308 offers the shooter every possible advantage to get the most from their rifle. From fit to finish, reliability of performance, and out of the box accuracy, the FD308 is the apex in AR refinement.
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 impengement rifle system.
This proprietary interface exerts 8200lbs of axial force against the upper receiver, compared to 6700lbs 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.
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.
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.
