Composite bolt action rifle stocks by Norwegian GRS Riflestocks have a very well-thought-out design and have been quite popular among hunters and shooters across the globe. Some firearm manufacturers even offer versions of their rifles equipped with these stocks. The latest example of such cooperation is the recently announced Mauser 18 Fenris rifle, an M18 that comes standard with the GRS Fenris stock.

Feared by gods. Tamed by heroes

MAUSER 18 Fenris

Uncompromising, powerful, robust: The new MAUSER 18 Fenris was named af- ter the wolf Fenrir from Norse mythology.

The ergonomic GRS stock with comb that can be height adjusted at the press of a button and the length adjustable recoil pad can be adapted to any situation in a matter of seconds. Whether in active hunting or at the shooting range: This “predator” puts hunters who focus on practical application and shooting prey at the ultimate end of the food chain.

GRS Fenris is the latest member of this family of composite stocks. The main difference of the Fenris from its siblings is the Honeycomb pattern on the grip and forearm. The GRS Fenris stock features a quick adjustable cheekpiece and length of pull, QD sling swivel sockets on the left side of the forearm and the buttstock, and a sling/bipod stud at the bottom of the forearm.

Note the Honeycomb pattern on the grip and forearm

The Mauser 18 Fenris bolt action rifle features a cold hammer forged barrel threaded with the metric M17x1 thread pitch and available in 47, 51, 56, and 62 centimeter (18.5″, 20″, 22″ and 24.4″) length options depending on the caliber. The rifle will be available in one of the following chambering options: .223 Remington, .243 Winchester, .270 Winchester, 6.5×55 Swedish, 6.5 PRC, 6.5 Creedmoor, .308 Winchester, .30-06 Springfield, 7x57mm Mauser, 8×57 IS, 7mm Remington Magnum, and .300 Winchester Magnum. The Mauser 18 Fenris is fed from four or five-round flush-fit detachable box magazines or extended 10-rounders. This rifle also features a three-lug bolt, three-position safety and 2.2-4.4 lb trigger pull weight. The overall weight is 3.6 kilograms (7 lbs 15 oz).

At the time of writing, no price information can be found on the manufacturer’s website and it’s unknown if this version of the M18 will be offered in the US market.

    No 7mm08, no care.

    The MSRP is probably in “if you have to ask, take out a loan” territory…

      @john huscio Given going rate for the existing Mauser 18 lineup it's probably more reasonable than you expect.

    Interesting product name.

    A repeating adapter for compound bow made its market debut as the “FENRIS” in 2020 … https://uploads.disquscdn.c...
