GRS Thumbhole, Blaser R8 Professional HB

• Thumbhole grip design: The thumbhole layout gives the firing hand a more natural, repeatable position, helping maintain control during field shooting and making it easier to stay steady from improvised rests, sticks, or prone positions.
• Adjustable cheek piece: A height-adjustable comb helps align the eye consistently behind the scope, which improves comfort and supports faster, more repeatable sight pictures with hunting optics.
• Laminate construction: The laminate build adds stiffness and stability, giving the stock a solid feel and helping it hold its shape well through regular hunting and range use.
• Glass-bedded platform: Glass bedding supports a stable action fit, which is especially useful for maintaining consistent accuracy and managing recoil with more powerful chamberings up to .375 HH.
• 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 comfort with enough substance for controlled shooting.

About the GRS Thumbhole Series

The GRS Thumbhole series was introduced as GRS's first thumbhole stock and remains part of the brand's laminate-stock range for shooters who want a more supportive grip shape than a conventional hunting stock. GRS positions the series for field hunting and range use, so the design focuses on practical control, repeatable shooting form, and straightforward adjustability rather than a highly specialized competition setup.

Across the range, the Thumbhole stocks are built from birch laminate with an oiled finish, giving them a solid, traditional feel while retaining the structural stability laminate is known for. The series also incorporates GRS SpeedLock adjustment, allowing quick stock fit changes without turning the rifle into a bulky chassis system. That makes the Thumbhole line a sensible choice for hunters and recreational precision shooters who want a stock that feels more supportive in the hand, offers a better cheek weld for scoped rifles, and still keeps the familiar handling of a classic sporting rifle.

About the GRS Thumbhole, Blaser R8 Professional HB

The GRS Thumbhole, Blaser R8 Professional HB is tailored for shooters who want to give the Blaser R8 Professional HB a more supportive stock geometry for hunting and general precision work. Its thumbhole layout promotes a straighter wrist angle and a more locked-in firing grip, which helps when shooting from uneven field positions or when trying to break clean, controlled shots at longer distances. That makes it well suited to alpine hunting, driven hunt, stalking, and woodland use, where shooting positions and time pressure can vary from one shot to the next.

The laminate construction gives the stock a firm, stable feel, while the glass bedding setup supports a secure interface between rifle and stock. In practical use, that matters because a stable bedding surface helps the rifle track more consistently under recoil and can support dependable zero retention. The stock also includes an adjustable cheek piece, which is one of the most useful upgrades for a scoped hunting rifle: it helps the shooter bring the eye into the same position behind the optic every time, reducing head lift and improving comfort during longer sessions.

With a 390.00 mm length of pull, 40.00 mm forend width, and 740.00 mm overall length, this model keeps a practical hunting profile rather than moving toward a wide, bench-oriented stock shape. At 1300.00 g, it adds enough substance for a planted shooting feel without becoming unnecessarily cumbersome in the field. The stock is rated up to .375 HH, underlining that it is built to handle serious hunting calibers as well as standard sporting chamberings.

About GRS

GRS began in 2010 in Grodås, Hornindal, Norway, and focuses on rifle stocks for hunting and shooting. The company grew out of a family business that started in 1983 as Grodås Møbler AS, a furniture manufacturer, which helps explain GRS's strong emphasis on stock shaping, ergonomics, and material work. GRS later began producing laminate rifle stocks in 2011 and expanded into composite stocks and aluminum chassis stocks as its product range developed.

Today, GRS Riflestocks AS is headquartered in Hornindal, Norway and is known for stock systems that combine practical field handling with user-adjustable fit. Its lineup includes the Hunter Light, Sporter, Bifrost, Fenris, Warg, and Ragnarok families, and the brand's GRS SpeedLock adjustment system is one of its defining features. In this category, GRS has built a reputation around giving hunting and shooting rifles a more adaptable fit without losing the solid feel expected from a purpose-built stock.
