About
What it is, and why it matters
The Sako 100 Explorer celebrates Sako's centenary with an innovative modular bolt-action rifle featuring a switch-caliber system and take-down design. The barrel-mounted scope ensures consistent accuracy even after disassembly and reassembly. Available with interchangeable wood and carbon fiber stocks, it represents Sako's vision for the future of hunting rifles.
The Sako 100 was designed to celebrate the company's 100th anniversary in 2021, embodying Sako's pioneering spirit with a completely new modular platform that reimagines what a hunting rifle can be.
The switch-caliber platform allows changing between multiple calibers in one rifle. Barrel lengths: 508mm and 620mm. Weight ranges 3.7-4.1 kg. Available with oiled walnut or carbon fiber stock. The take-down feature enables compact transport.
