Sako Quad is a bolt-action rifle made by the Finnish firearms manufacturer Sako. Quad is delivered in many configurations, and has a quick change barrel system which lets the user swap barrels using a 5 mm hex key.[2] The bolt lift is 50 degrees.[3] Sako Quad factory barrels are delivered chambered for .17 Mach 2 (.17 HM2), .22 LR, .17 HMR and .22 WMR. There are two types of magazines, one type for the shorter .17 M2 and .22 LR, and another for .17 HMR and .22 WMR.[4]
Visually, the Sako Quad has many similarities with Sako Finnfire.[5] The Quad is delivered with a blued receiver and barrel, and the barrels are color coded according to their chambering. In cooperation with Sako, Burris has developed a scope sight with corresponding color coding on its elevation turret to match the ballistics of the different cartridges.
