Also known as: Sako Quad Combo, Sako Quad Range
Overview
The Sako Quad is a Finnish bolt-action rimfire rifle introduced in 2005 with a defining feature unique among production rimfires: a tool-change interchangeable-barrel system that allows the same receiver and stock to be re-chambered in seconds between four different rimfire cartridges - .22 Long Rifle, .22 Winchester Magnum Rimfire, .17 Hornady Magnum Rimfire, and .17 Mach 2. The user inserts a special tool, turns it three full rotations, tilts the barrel up to release the action, and slots in another barrel; point of impact is retained between swaps. Two magazine bodies are supplied (one for the shorter .22 LR / .17 Mach 2 case, one for the longer .22 WMR / .17 HMR), and either a wood or synthetic stock with a Monte Carlo cheekpiece is available. The Quad was discontinued circa 2017, replaced in the Sako rimfire lineup by the simpler single-caliber Finnfire II.

Notes
Specifications shown are typical for the Heavy Barrel model with the .22 LR barrel installed (560 mm / 22"). Barrel is 6-groove, 1:9" twist on the .17 HMR barrel and 1:16" on .22 LR. Weight varies by stock/barrel combination from approximately 2.6 kg (Sporter wood) to 3.5 kg (Heavy Barrel synthetic). Replacement barrels were sold as accessories for users who initially bought the rifle in only one caliber.
Background
The Quad was the only mainstream production bolt-action rimfire ever sold with a true four-caliber switch-barrel system - one rifle, four cartridges, no gunsmith required. Sako engineered the breech and barrel-collar interface so precisely that point of impact was retained after a barrel swap, making it possible for a hunter to carry a single Quad receiver and switch between subsonic .22 LR for rabbits, .22 WMR for fox, .17 HMR for long-range varmints, and .17 Mach 2 for inexpensive plinking - all in the same morning.
