Overview

GRS Riflestocks is a Norwegian firearm-accessories manufacturer headquartered and producing near Grodås in Volda Municipality, Møre og Romsdal. The company is known primarily for rifle stocks shaped around ergonomic adjustment and shooting comfort, including laminate, composite, and aluminium chassis products for a range of bolt-action rifles and other firearm platforms. The business began in 1983 as Grodås Møbler AS, a furniture factory founded by Anne-Lise and Oddvin Haugen. Its early production took place in the founders' home before moving in 1985 to dedicated factory premises. During the 1990s, the company increased the use of automated CNC machinery, developing manufacturing capabilities that later proved useful when it diversified beyond furniture. During the 2000s, the founders' sons, Håvard and Oscar Haugen, took over the company. The 2008 financial crisis created difficulties for the furniture operation and encouraged the company to seek a new market. GRS subsequently developed rifle stocks, launching its first ergonomic laminate models in 2011. This transition became the defining turning point in the company's identity and led to the adoption of the GRS Riflestocks name in the market. GRS's products emphasize adjustability and handling. Its laminate stocks have included the Hunter, Sporter, Hybrid, Varmint, and Decima designs. Common features include adjustable cheekpieces and adjustable length of pull, marketed by the company as the Speed Lock system. Stocks have been supplied either with inlets prepared for particular rifle actions or as blanks requiring gunsmith fitting. The product range expanded from traditional stocks into chassis and composite constructions. The Bolthorn aluminium chassis, introduced in 2014, added an adjustable pistol grip and compatibility with AICS magazines. The Bifrost composite stock followed in 2016, using glass-fiber reinforcement and the Speed Lock system. In 2018, GRS introduced the Berserk composite stock with a different composite construction and the SpeedLock 2 adjustment concept. The Ragnarok chassis and Warg hybrid stock were introduced in 2019, extending the range to platforms including Blaser rifles and other bolt-action models. In 2015, Innovation Norway named GRS Riflestocks its company of the year. By 2020, the company had more than 20 employees and distributors in over 45 countries. Available reference material identifies the business as a Norwegian manufacturer with international distribution, but does not provide a current ownership structure, revenue figures, official website, or a complete current executive roster.

History

GRS Riflestocks developed from a Norwegian furniture company founded in 1983. Anne-Lise and Oddvin Haugen established the business under the name Grodås Møbler AS. Initially, furniture was made in the founders' own home. In 1985, production moved into a dedicated factory near Grodås in what is now Volda Municipality, in Møre og Romsdal county. The company modernized its manufacturing during the 1990s, introducing substantial automation and CNC machinery. This created a more technically controlled production environment and gave the business capabilities that later supported the manufacture of shaped firearm stocks. During the 2000s, the founders' sons, Håvard and Oscar Haugen, took over the company. The 2008 financial crisis placed pressure on the furniture operation. In response, the company decided to enter the rifle-stock market as a way to reach a new customer segment. GRS launched its first rifle stocks in 2011. These were ergonomic laminate designs intended to improve adjustability and shooting comfort, distinguishing the new business from conventional fixed rifle stocks. The initial range developed into several laminate models, including Hunter, Sporter, Hybrid, Varmint, and Decima. The stocks incorporated adjustable cheekpieces and adjustable length of pull, a feature GRS calls Speed Lock. The company supplied products with inlets for specific firearm models and also offered blanks that could be fitted by gunsmiths. Tikka T3 was among the rifle platforms for which prepared inlets were available. GRS broadened its construction methods in 2014 with the Bolthorn aluminium chassis. The chassis was offered for platforms including the SIG Sauer 200 STR and SSG 3000, Remington 700 short-action and long-action configurations, Howa 1500 short-action and long-action configurations, and Tikka T3. It retained the Speed Lock concept, added an adjustable pistol grip, and used AICS-pattern magazines. The company continued its expansion into composite products. The Bifrost, launched in 2016, used glass-fiber reinforcement and retained Speed Lock adjustment. The Berserk followed in 2018, using a different composite construction and introducing the SpeedLock 2 adjustment system. In 2019, GRS launched the Ragnarok chassis for Blaser R8 and R93 rifles and the Warg hybrid stock for several other bolt-action models. These products extended the brand's range across traditional stocks, hybrid designs, and chassis systems. Innovation Norway recognized GRS as its company of the year in 2015. By 2020, GRS had more than 20 employees and distributors in over 45 countries. Its headquarters and production facilities remained near Grodås. The available reference material does not establish a current chief executive, ownership arrangement, financial performance, official website, or subsequent product history, so those details remain unconfirmed.
