This Mountaineer pairs a robust fluted stainless heavy-profile barrel with a 1:28 twist for consistent performance. The 27.5 in barrel length and stainless construction emphasize durability and stability, complemented by a stainless finish throughout.
The laminated hardwood stock in gray/black features a thumbhole design and a Monte Carlo cheekpiece for a steady, repeatable hold. A ventilated fore-end, recoil pad, and sling swivel studs round out a stock set made for practical field handling with a 13.5 in length of pull.
Its inline system uses a tool-less knurled breech plug for straightforward maintenance and 209 primer ignition. Controls include a manual safety and a secondary bolt-shroud safety, with a teardrop/round bolt knob and single-shot capacity.
For mounting solutions, the receiver and barrel are drilled and tapped, including two positions on the barrel, and two-piece aluminum scope bases come installed. There are no iron sights. An under-barrel ramrod with a brass jag is included and installed. The barrel is marked MADE IN USA.
