GRS Thumbhole, Blanks

• Thumbhole Ergonomics: The thumbhole grip gives the firing hand a relaxed, repeatable position that helps maintain control from field positions and supports steadier trigger work on hunting rifles.
• Adjustable Cheek Piece: An adjustable cheek piece makes it easier to align the eye naturally behind the scope, improving comfort and helping the shooter return to the same head position shot after shot.
• Laminated Construction: The laminate build adds stiffness and stability, which is useful in changing outdoor conditions where a stock must keep its shape and support consistent rifle handling.
• Glass Bedding Interface: The glass-bedding design supports a more secure action fit, helping the rifle maintain consistency and making the stock well suited to accurate hunting and range use.
• Field-Ready Dimensions: With a 390.00 mm length of pull, 40.00 mm forend width, and 1300.00 g weight, the stock balances practical carry weight with enough substance for stable shooting.

About the GRS Thumbhole Series

GRS Thumbhole is the company’s first thumbhole stock and remains part of its laminate-stock range for hunters and shooters who want a more locked-in grip shape than a conventional sporter stock. GRS positions the series for both field hunting and range use, so the design has to balance practical carry, stable handling, and repeatable shooting positions. The stock is made from birch laminate with an oiled finish, giving it the stiffness and traditional feel many shooters want in a hunting stock while keeping the profile suitable for real outdoor use.

A defining feature of the series is GRS SpeedLock adjustment, which allows the stock to adapt more easily to different shooters, optics heights, and clothing layers. That matters in practice because a rifle that fits correctly is easier to mount quickly and easier to shoot consistently from improvised positions. The Thumbhole line is offered in several color options, including Brown, Green Mountain Camo, Nordic Wolf, Orange, and Black, and it is produced in multiple inlets for popular rifle brands. Within the GRS lineup, the Thumbhole series serves shooters who want laminate construction, classic lines, and a more supportive grip geometry for hunting rifles.

About the GRS Thumbhole, Blanks

GRS Thumbhole, Blanks is a hunting rifle stock built for shooters who want the control of a thumbhole design without moving to a heavier competition-style platform. Its shape is especially useful for alpine hunting, driven hunt, stalking, and woodland hunting, where the rifle may be carried for long periods but still needs to come to the shoulder naturally. The thumbhole grip helps the hand settle into a repeatable position, which can improve comfort during deliberate shots and support steadier trigger control when shooting from uneven field rests.

The stock uses laminate construction and a glass bedding interface, a combination that favors structural stability and a secure action fit. In practical terms, that means the stock is designed to support consistent rifle behavior while standing up to regular hunting use. The adjustable cheek piece is one of the most important functional details, because it helps the shooter achieve proper eye alignment with a mounted scope instead of lifting or rolling the head to find the sight picture. With a 390.00 mm length of pull, 40.00 mm forend width, and 740.00 mm overall length, the stock keeps a field-oriented format that remains manageable in the hand and on the shoulder. Its 1300.00 g weight gives it enough mass for stable handling without pushing it out of the hunting category, and the stock is rated for calibers up to .375 HH.

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 stock shape, fit, and handling rather than treating a rifle stock as a simple shell. Today, GRS Riflestocks AS is headquartered in Hornindal, Norway and specializes in rifle stocks for both hunting and shooting applications.

The company produces laminate, composite, and aluminum chassis stocks across product lines such as Hunter Light, Sporter, Bifrost, Fenris, Warg, and Ragnarok. GRS began making laminate rifle stocks in 2011, and adjustment systems such as GRS SpeedLock have become closely associated with the brand. In this category, GRS is known for combining ergonomic stock geometry with practical adjustability, giving shooters a better fit to the rifle without losing the field-ready character expected from hunting equipment.
