The Defiance Machine anTi X action anchors this build, delivering a smooth, precise bolt throw with a spiral-fluted bolt and a grooved knob for confident manipulation. The receiver is fitted with two short Picatinny scope base sections, providing a solid mounting interface for the buyer’s chosen optics setup.
The 20-inch carbon-fiber wrapped barrel keeps the profile trim while maintaining rigidity, and it features a stainless steel muzzle section with a bare crown. In 6mm Creedmoor, the chambering aligns with the rifle’s precision-focused configuration.
The MDT HNT26 chassis combines a carbon-fiber forend and buttstock with a folding butt hinge, foam cheek piece, and a rubberized recoil pad. M-LOK style slots on the forend and a short underside accessory rail support direct mounting of compatible accessories. The AR-style MDT vertical pistol grip provides a familiar control interface.
A detachable box magazine system feeds the rifle, and this example includes an MDT 5-round AICS-pattern magazine, with a stated capacity of 5+1. The length of pull measures 13 inches, and the chassis features a carbon-fiber construction to complement the barrel’s carbon wrap.
