The build centers on the Defiance Machine anTi titanium long action, combining light weight with strength. The two-lug bolt uses a plunger-style ejector, and the spiral-fluted bolt body, swept handle, and cylindrical grooved knob provide smooth cycling and confident control. The receiver wears a matte dark gray/black finish.
Its 26-inch Sendero-contour, carbon-fiber–wrapped heavy barrel is threaded and fitted with an MDM tri-port muzzle brake to help manage recoil. The 1:9 twist is set up for a broad range of .300 Win. Mag. bullet weights, and the barrel shank is marked "LRI."
The Pure Precision Altitude carbon-fiber composite stock pairs a camo/textured finish with a right-hand cheekpiece, vertical/palm-swell grip, and a Decelerator buttpad. Dual front sling swivel studs and a rear stud are installed. Bottom metal is H-S Precision DBM with a detachable magazine, and length of pull measures 14.0 inches.
Fire control is via a TriggerTech Diamond single-stage trigger with a curved shoe. Up top, a Murphy Precision titanium one-piece Picatinny rail is installed for secure scope mounting. The rifle feeds .300 Winchester Magnum from a 3+1 configuration and is set up as a long-action platform made in the United States.
