GRS Warg Composite Stock, Bergara B14 SA HMR M5

• Composite long-range stock: The GRS Warg combines a rigid composite body with a practical field shape, giving a Bergara B14 short action a more stable platform for hunting and extended-range shooting.
• M-Lok aluminum fore-end: The fore-end is built to accept accessories such as a bipod or front-mounted thermal equipment, making it easier to configure the rifle for prone work, supported shooting, or mixed hunting use.
• SpeedLock II adjustability: Tool-free adjustment of length of pull and cheekpiece height helps the stock fit different shooters, optics heights, and shooting positions, improving head position and repeatable sight alignment.
• No bedding required: The inlet is designed to install without bedding, which simplifies the build process and helps shooters upgrade to a more capable stock without additional gunsmithing steps.
• Built for real field use: With a 1350.00 g weight, 807.00 mm overall length, and a varmint barrel channel, this stock balances carry comfort with the stability needed for deliberate shooting.

About the GRS Warg Series

GRS Warg sits in the brand’s composite and chassis range and is aimed at shooters who want a stock that bridges hunting use and long-range work. The series is built around a fiberglass-reinforced body paired with an aluminum fore-end patterned for M-Lok accessories, giving it a more modular front end than a conventional hunting stock. That layout makes the Warg especially suitable for rifles that may carry a bipod, additional support equipment, or front-mounted thermal devices.

A defining feature of the series is the SpeedLock II adjustment system, which allows the stock to be tailored for cheekpiece height and length of pull without turning it into a bulky target chassis. GRS positions the Warg as a stock for long-range shooting and hunting, so the design focuses on practical ergonomics, stable support from field positions, and straightforward installation. The series is also made in rifle-specific inlets for multiple actions, and GRS states that bedding is not required, which keeps the upgrade process simpler for shooters building a more capable rifle around a proven action.

About the GRS Warg Composite Stock, Bergara B14 SA HMR M5

The GRS Warg Composite Stock, Bergara B14 SA HMR M5 is configured for a right-hand Bergara B14 short action HMR M5 footprint and is intended for shooters who want more adjustability and accessory support than a standard factory stock. Its stated applications of alpine hunting, stalking, and woodland show that this is not a bench-only design; it is meant to carry in the field while still giving the rifle a more planted feel when shooting from prone, a bipod, or improvised support.

The stock uses a composite construction and weighs 1350.00 g, which helps keep the rifle manageable while adding the stiffness needed for consistent support. The 380.00 mm length of pull and adjustable cheekpiece make it easier to set up proper eye alignment behind a scope, especially when optic height, clothing layers, or shooting position change. The 47.00 mm fore-end width gives a broad, stable contact area for bags and supported positions, while the varmint 0,86 in (22 mm) diameter barrel channel suits heavier-profile barrels often chosen for precision-oriented hunting rifles.

GRS also specifies that bedding is not required, which simplifies installation, and the recommended 5.20 nm torque setting helps the action seat correctly in the stock. With a maximum caliber rating of .378 Weatherby, the design is built to handle substantial recoil, and because the stock is non-folding, it keeps a straightforward fixed-stock layout that favors rigidity and simplicity over extra moving parts.

About GRS

GRS began in 2010 in Grodås, Hornindal, Norway, growing from a family business that started in 1983 as Grodås Møbler AS, a furniture manufacturer. That background helps explain the company’s emphasis on stock shape, fit, and ergonomics. GRS specializes in rifle stocks for hunting and shooting and produces laminate, composite, and aluminum chassis designs for a wide range of rifle platforms.

Within its lineup, GRS offers series such as Hunter Light, Sporter, Bifrost, Fenris, Warg, and Ragnarok, covering everything from lighter hunting setups to more competition-oriented rifles. One of the brand’s notable technologies is SpeedLock, its adjustment system for rifle stocks, developed to let shooters adapt fit quickly and repeatably. GRS remains headquartered in Hornindal, Norway and is best known for combining practical field ergonomics with stocks intended for modern hunting and precision shooting use.
