About
What it is, and why it matters
The Sako S20 Precision is a modern modular bolt-action rifle from Finland's legendary Sako firearms manufacturer, designed to bridge the gap between hunting and precision competition shooting. Featuring Sako's cold hammer-forged barrel in a medium-heavy match contour with 20mm outer diameter and 5/8-24 UNEF threaded muzzle, the S20 Precision delivers exceptional accuracy from a remarkably lightweight platform at just 3.3 kg. The rifle's defining feature is its modular architecture: the receiver, barrel, stock, and forend can all be quickly swapped or reconfigured without specialized tools, allowing shooters to adapt the rifle to different disciplines. The adjustable trigger offers a pull weight range of 1-2 kg, and the aluminum chassis stock with polymer furniture provides a rigid, repeatable platform with adjustable cheek piece and buttpad. The M-LOK forend accepts accessories while maintaining a clean, snag-free profile.
The S20 marked a bold departure for Sako, a company with over a century of traditional bolt-action rifle craftsmanship. By embracing modularity and modern chassis design while retaining their renowned cold hammer-forged barrel quality, Sako created a rifle that appeals to both competition precision shooters and hunters seeking a single adaptable platform.
The Sako S20 platform was introduced in February 2020 as Sako's first modular rifle system. The Precision model with heavier barrel contour followed. Available in numerous calibers from .243 Win to .300 Win Mag. MSRP approximately $1,725-$2,000.
