A paradigm shift in function and design, the X-3 was redesigned to be a gas piston system. Carrying over lessons learned from the X-1 and X-2 designs, the X-3 represented a significant leap forward in weight distribution, heat dispersion and reduction in recoil. The X-3 recoil was reduced by more than half that of the X-1 and X-2 and improved target acquisition on follow up shots drastically.
Maintenance requirements were reduced significantly through a combination of the gas and heat dispersion towards the front of the rifle and the revolutionary UmbraTec coating.
The X-3 introduced a new monolithic, all-aluminum, full weapons length, MIL-STD 1913 picatinny free floating rail system which provided a truly dynamic platform for mission specific accessories that could be mounted or removed at any of the 7 positions around the rail and any place along the length of the tube to provide an almost 360 degrees of placement around the tube. This carried over to the current variant in service today.
