Overview:
As one of the lightest bolt-action rifles on the market, the 90 Peak is an ideal choice for the decerning mountain hunter. The lightweight of the 90 Peak is largely thanks to Sako’s innovative carbon fiber stock design. These synthetic stocks are made using a Resin Transfer Molding (RTM) – a technology used by the aerospace industry for structures that need to be both strong and lightweight. RTM technology uses precisely machined molds and a vacuum technique to bond resin and carbon filaments, creating a multi-layered 3D mesh structure that surrounds the stock in every direction. The result is a solid foundation that easily withstands heavy sustained recoil and promotes accuracy. The RTM stock also features a textured surface for a superior grip in adverse weather conditions, a palm swell to fill the shooter’s hand, and a raised cheek piece.
Receiver:
Like all of the rifles in Sako’s 90 series, the Peak is built around the 90 Receiver. As the heart of the rifle, these receivers are designed using a unique broaching method to minimize the contact area between the bolt and receiver. The is made possible by creating an internal surface that matches the profile of the bolt locking lugs. To achieve this, the steel of the receiver is carved by pushing multiple bolt-shaped cutting tools through the receiver to create a straight interior surface. The result of this manufacturing process is one of the smoothest operating bolts available – an essential feature when fast repeated shots are required. The 90 receiver has also been reinforced from previous models to easily withstand heavy recoil and promote superior accuracy. Torsional bending and twisting have been minimized by designing the specific shapes for critical areas, and flat receiver bedding provides better repeatable accuracy than a conventional round receiver design. Furthermore, the 90 Peak’s receiver features integrated picatinny rail sections for virtually unlimited optics-mounting options.
Bolt:
The innovative design and construction of the receiver is perfectly complemented by the bolt. The bolt’s ultra-short throw goes hand in hand with the smooth operation, making follow up shots nearly instantaneous. To ensure reliability extraction, the bolt features a dual plunger design similar to the one found on Sako’s sniper rifles. This bolt design is ideal for dangerous game, and was verified by cycling the bolt over 5 million times without any malfunctions.
Barrel:
All Sako 90 rifles are equipped with a cold hammer forged barrel. Like the receiver’s manufacturing process, Sako’s cold hammer forging process results in a smoother surface when compared to other rifling methods. Because the steel cannot escape when hitting against the mandril, it creates a smooth, straight, and uniform surface, enabling out-of-the-box-accuracy and completely eliminates the needed for a break-in process. These match-grade barrels also utilize an innovative muzzle-crowning process to enable the pressure to escape the muzzle evenly, thus improving accuracy. Crowns are protected from external hits by a recessed shape, and absolute geometrical uniformity of the crown is mandatory for accurate operation of the rifle. The 90 Peak’s barrel in particular features fluting to help dissipate heat generated from multiple shots.
