GRS Sporter Laminate Stock, Mauser M25

• Adjustable fit with SpeedLock ergonomics: The GRS Sporter uses an adjustable cheekpiece and length of pull to help the rifle sit correctly behind the shoulder and eye, giving a more repeatable head position and steadier sight alignment in both hunting and competition shooting.
• Birch laminate construction: The laminate stock combines stiffness with good dimensional stability, which helps maintain consistent handling across changing weather conditions while also giving the rifle a solid, planted feel.
• Varmint barrel channel: The 0,86 in (22 mm) barrel channel is suited to heavier barrel contours, making this stock a practical choice for rifles set up for precision work as well as field use.
• Ergonomic grip and textured contact surfaces: The grip shape and added texture support secure hand placement and better trigger control, especially when shooting from improvised positions or during fast follow-up shots.
• Built for mixed-use shooting: With a right-hand configuration, glass-bedding setup, and applications spanning competition, driven hunt, and stalking, this stock is designed to bridge field carry and deliberate shooting.

About the GRS Sporter Series

The GRS Sporter series is built around the idea of one stock covering several roles well, rather than being limited to only hunting or only range use. In the GRS lineup, it sits as an all-round laminate stock for shooters who want more adjustment and a more supportive grip shape than a conventional factory stock. The series is based on a birch-laminate construction and is intended for applications such as driven hunts, stalking, and competition shooting, which explains its balance of field-friendly handling and target-oriented ergonomics.

A defining feature of the series is GRS SpeedLock, paired with an adjustable cheekpiece and adjustable length of pull. That combination lets the rifle be fitted more precisely to the shooter, which helps with eye alignment, recoil consistency, and a more natural shooting position across prone, supported, or offhand use. The Sporter series is also known for its ergonomic grip geometry and broad practical appeal, making it a common choice for shooters who want a laminate stock that can support both hunting optics and more precision-oriented rifle setups.

About the GRS Sporter Laminate Stock, Mauser M25

The GRS Sporter Laminate Stock, Mauser M25 adapts the Sporter concept to the Mauser M25 platform with a layout suited to shooters who want one rifle to cover hunting and structured range work. Its laminate construction gives the stock a firm, stable feel, while the 1380.00 g weight keeps enough mass in the system to support steadier shooting without turning the rifle into an overly heavy field setup. At 760.00 mm overall length, it maintains the familiar Sporter proportions that balance support at the front with a compact rear section.

The practical advantage of this model comes from fit adjustment. A 363.00 mm length of pull and adjustable cheekpiece help the shooter set the rifle up for a more repeatable cheek weld and more natural eye position behind the optic. That matters in stalking and driven hunting, where quick sight acquisition is important, but it also pays off in competition by improving consistency from shot to shot. The 53.00 mm forend width offers a supportive surface for bags, rests, and improvised field positions, while the added grip texture helps maintain control in wet or cold conditions.

This Mauser M25 version is also configured for more demanding rifle setups. The Varmint 0,86 in (22 mm) diameter barrel channel accommodates heavier barrel contours, and the glass bedding arrangement supports a more stable action-to-stock interface. With a stated max caliber of .375 HH, the stock is built for serious use, and the recommended 3.50 nm torque setting helps the action seat consistently after installation or maintenance.

About GRS

GRS began in 2010 in Grode5s, Hornindal, Norway, growing out of a family business that started in 1983 as Grode5s Mf8bler AS, a furniture manufacturer. That background is relevant because GRS focuses on rifle stocks where shaping, ergonomics, and material work matter as much as mechanical fit. The company specializes in rifle stocks for hunting and shooting and produces laminate, composite, and aluminum chassis stocks for a wide range of rifle platforms.

Within this category, GRS is especially known for its emphasis on shooter fit and practical field ergonomics. Its stocks use features such as the GRS SpeedLock adjustment system and distinctive grip geometry to help shooters achieve a more repeatable position behind the rifle. The companys product families include Hunter Light, Sporter, Bifrost, Fenris, Warg, and Ragnarok, covering traditional hunting stocks through to more competition-oriented chassis designs.
