As one of the lightest bolt-action rifles on the market, the 90 Peak is an ideal choice for the discerning 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.
