The S20 Hunter features an ergonomic thumbhole stock that is packed with features any hunter will appreciate. Using spacers on the buttpad, the S20 Hunter allows the shooter adjust their length of pull and the numbered quick-adjust cheekpiece ensures the hunter will always have their ideal sight picture when shouldering their rifle. The S20 Hunter also features a specially designed five round Cartridge Plus magazine (three for magnum calibers), that provides extra length for reloaders. Additionally, the S20 Hunter features quick-detach points for mounting sling hardware on both sides of the stock and soft-touch inserts on the forend and pistol grip.
The Sako S20's stainless steel action is brand new and features a 3-lug, push feed bolt with plunger ejection to maximized reliability. The Cerakoted receiver of the S20 features a machined Picatinny rail that allows for the easy mounting of riflescopes. The trigger of the S20 is adjustable for pull weight and for position within the trigger guard (± 7mm) to ensure an absolute perfect length of pull for the shooter. The barrel of the S20 is made from stainless steel and fluted to reduce weight and barrel cool down time. The muzzle of the rifle is 5/8x24 threaded, allowing for the addition of muzzle devices like suppressors or brakes.
