6mm arc in an ar16 platform by davidson defense

The 6mm ARC is a medium-power cartridge comparable to the 6.5mm Grendel, but with better ballistics thanks to the greater muzzle velocity achieved by using lighter 6 mm bullets and enough power to make use of the heavy 6 mm bullets. Some have stated that it offers comparable ballistics to larger 6 mm cartridges like the 6mm Creedmoor and .243 Winchester, but out of a smaller cartridge, however this simply is not true when comparing muzzle velocities between them.[6] What the 6mm ARC does offer though is almost comparable velocities and ballistic performance, but out of a compact cartridge that has lessened perceived recoil and fits into the standard AR-15 length actions.
