GRS Sporter Laminate Stock, Mauser M18

• SpeedLock adjustment system: Push-button adjustment for the cheekpiece and length of pull makes it easier to set the rifle up for a stable head position and repeatable shoulder placement, which helps maintain consistent eye alignment and recoil control.
• Laminate construction: The birch-laminate stock combines stiffness with good dimensional stability, giving the rifle a solid feel in changing weather and supporting dependable bedding for hunting or match use.
• Varmint barrel channel: The 0,86 in (22 mm) diameter barrel channel is suited to heavier barrel contours, giving this stock broader compatibility for rifles set up for precision shooting as well as general field use.
• Ergonomic sporter layout: A textured grip and practical forend width of 53.00 mm promote secure handling from field positions, barricades, or the bench without making the stock bulky to carry.
• Built for mixed use: Designed for competition, driven hunt, and stalking, this stock balances adjustability, manageable weight, and a traditional stock format for shooters who want one rifle to cover several roles.

About the GRS Sporter Series

The GRS Sporter series is GRS’s all-round birch-laminate stock family, intended for shooters who want a traditional stock shape with more fit adjustment than a fixed hunting stock can offer. In the manufacturer’s lineup, the Sporter sits as a versatile option for both hunting and competition shooting, rather than being limited to only one discipline. GRS specifically positions it for driven hunts, stalking, and competition, which explains its combination of practical field handling and shooter-fit features.

A defining characteristic of the series is GRS SpeedLock, which allows quick adjustment of the cheekpiece and length of pull. That matters because a rifle that fits the shooter properly is easier to mount consistently, especially when switching between optics, clothing layers, or shooting positions. The Sporter format keeps the familiar feel of a sporter stock, but adds the adaptability needed for more precise head position and better recoil management. The series is also offered in multiple color options, and its laminate construction reflects GRS’s focus on stocks that combine a solid, rigid feel with the durability needed for regular hunting and range use.

About the GRS Sporter Laminate Stock, Mauser M18

The GRS Sporter Laminate Stock, Mauser M18 brings the Sporter concept to the Mauser M18 platform with a layout that suits both hunting optics and precision-oriented rifle setups. Its laminate construction gives the stock a rigid, planted feel, while the glass bedding interface supports a stable action fit for shooters who want consistent accuracy from the rifle. Because this version is built with a varmint 0,86 in (22 mm) diameter barrel channel, it is especially relevant for M18 rifles configured with heavier barrels, where extra clearance and a more substantial stock profile are useful.

The practical strength of this model is its adjustability. With an adjustable cheekpiece and a 363.00 mm length of pull, the stock can be set up to give a more natural eye position behind a scope and a more repeatable shoulder mount. In real use, that helps the shooter settle faster on target and maintain the same position from shot to shot, whether shooting from standing positions on a driven hunt or from supported positions at the range. The right-hand configuration, textured grip surfaces, and 53.00 mm forend width all contribute to secure handling without making the stock feel oversized.

At 1380.00 g and 760.00 mm overall length, this stock stays manageable for a rifle that may be carried in the field but still needs the stability expected for deliberate shooting. Its stated 3.50 nm torque setting and .375 HH maximum caliber rating underline that it is built as a serious working stock, not just a cosmetic replacement.

About GRS

GRS traces its history to 2010 in Grodås, Hornindal, Norway, while the family business behind it began earlier, in 1983 as Grodås Møbler AS, a furniture manufacturer. That background helps explain why GRS developed a strong reputation for shaped laminate rifle stocks with careful attention to ergonomics and finish. The company began producing laminate rifle stocks in 2011 and has since expanded into composite stocks and aluminum chassis designs.

Today, GRS Riflestocks AS remains headquartered in Hornindal, Norway and focuses on rifle stocks for hunting and shooting. Its product range includes series such as Hunter Light, Sporter, Bifrost, Fenris, Warg, and Ragnarok. Across these lines, GRS is particularly known for practical fit-adjustment systems such as SpeedLock, which are designed to improve rifle fit without abandoning the straightforward handling that hunters and target shooters expect.
