The Steyr Mannlicher Pro THB offers a modern compliment to other traditional platforms. A durable synthetic stock resists weather and rough use and features removable spacers in the butt of the stock to adjust length of pull. - The Pro Hunters heavy barrel is available in 16 20 or 26 with Mannox finish and the rifle is chambered in .308 Winchester. The barrel comes with 5/8x24 right-hand thread and has a tactical bolt knob. The standard heavy barrel comes with a 20MOA picatinny rail but a long picatinny rail is also available. - As in other high-performance long-guns offered by Steyr the Mannlicher Pro THB features the Safe Bolt System (SBS) a unique 2+1 safety function that offers 3 settings operated by a wheel switch on the tang of the stock. The fire mode (safety off) is indicated by a red dot; the first level of safe mode disables the firing mechanism and the second level of safe serves to lock the bolt down against the stock and also features a press-to-release tab that locks the SBS switch in the safe position. - Another feature is the 2-stage magazine securing mechanism that uses a first stage that locks the magazine in but allows the bolt to be operated while not engaging and chambering the rounds in the magazine thereby providing the operator with the option of loading individual rounds by hand while maintaining a full magazine at the ready. One more tap to the bottom of the magazine then seats it in the second stage which is ready for auto-loading.
