GRS Thumbhole, Sauer 100

• Thumbhole Ergonomics: The thumbhole layout promotes a relaxed, repeatable hand position that helps steady the rifle in field positions and on the range, especially when shooting from improvised rests.
• Adjustable Cheek Piece: Built-in cheek piece adjustment makes it easier to align the eye naturally behind the optic, improving comfort and helping maintain a consistent sight picture from shot to shot.
• Laminate Construction: The laminate build gives the stock a solid, stable feel with good resistance to changing weather conditions, which is valuable for hunting rifles used across different seasons.
• Glass Bedding Interface: A glass-bedding setup supports a more secure action fit, helping the rifle maintain consistent contact surfaces for dependable accuracy potential.
• Field-Oriented Design: With applications ranging from stalking and woodland hunting to driven hunt and alpine use, this stock balances practical handling with the control needed for deliberate shooting.

About the GRS Thumbhole Series

The GRS Thumbhole series is the company’s first thumbhole stock family and forms part of its laminate-stock range for hunters and recreational or precision-minded shooters who want more control than a conventional factory stock typically provides. GRS positions the series for field use and range shooting, which explains its blend of classic stock lines with a more supportive, ergonomic grip shape.

Across the range, the Thumbhole stocks are made from birch laminate with an oiled finish, giving them a traditional appearance while retaining the dimensional stability that laminate construction is known for. The series also incorporates GRS SpeedLock adjustment, allowing the fit of the rifle to be tailored more quickly than with fixed-stock designs. Offered in finishes such as Brown, Green Mountain Camo, Nordic Wolf, Orange, and Black, the Thumbhole line spans multiple rifle platforms and is intended for shooters who want a stock that feels equally at home in hunting terrain and during extended practice sessions.

About the GRS Thumbhole, Sauer 100

The GRS Thumbhole, Sauer 100 adapts the Thumbhole concept to the Sauer 100 action, giving that rifle a more supportive stock shape for hunting and general shooting use. Its thumbhole grip encourages a natural wrist angle and firmer rear-hand control, which is particularly useful when shooting from standing, kneeling, or supported field positions. For a rifle used across stalking, woodland hunting, driven hunt, and alpine hunting, that extra control can make the rifle feel steadier without making the stock overly specialized.

The stock uses laminate construction and weighs 1300.00 g, a combination that helps provide a planted feel while remaining practical for a hunting rifle. The adjustable cheek piece is one of the most important functional upgrades over a fixed stock, because it helps the shooter achieve more consistent head position behind a scope. That matters not only for comfort, but also for repeatable eye alignment and more confident shot execution in changing terrain.

With a 390.00 mm length of pull and 40.00 mm forend width, the stock is shaped to offer a stable front-hand hold and a balanced overall feel. The glass bedding arrangement supports a precise action fit, which is especially relevant for shooters looking to get the most from the Sauer 100 platform. GRS rates this inlet up to .375 HH, showing that the stock is built for serious hunting calibers as well as standard chamberings.

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 places so much emphasis on stock shape, fit, and handling rather than treating a rifle stock as a simple structural part.

Today, GRS Riflestocks AS is headquartered in Hornindal, Norway and specializes in rifle stocks for hunting and shooting. Its range includes laminate, composite, and aluminum chassis designs, with product families such as Hunter Light, Sporter, Bifrost, Fenris, Warg, and Ragnarok. A key part of the brand’s identity is its focus on practical ergonomics and user-adjustable fit, including the GRS SpeedLock system used on selected models.
