During our visit to NRA UK shooting range in Bisley, we had the chance to put our hands on one of the most precision custom-built rifle in Europe.
Walküre (Or as it is known in the UK as NIMROD) is a precision rifle made in Bavaria, Germany. The owner and founder of AS.H is Andres Schuler a very well known gunmaker and inventor in Germany. Their flagship is a self-constructed Precision Rifle gun (PSG) Valkyrie.

They incorporate a self-developed system when designing this rifle, decided to make this compatible in important areas with the Remington 700 system. They have paid attention to the compatibility especially in the interface shaft system, shanks, magazines and prints. However, they integrated the recoil cleat into their system at the interface shaft system in order to meet the exact requirement for precision. Also, the system comes with an integrated Picatinny rail which is a great advantage. The action is fashioned from tool steel that has a tensile strength of 1200N/mm2 and is then gas nitride finished with a phosphate and polyurethane coating. The bolt action uses a 3-lug operating system that locks into a central action ring embedded into the action body. Each lug is 0.54” long and 0.35” wide and offers near 100% contact when engaged, which is impressive and certainly aids accuracy. It has a 60° bolt lift and is 7” long with a solid 0.84” inch O/D, with nine, radial flutes to reduce bearing surface and to reduce any unwanted binding due to debris falling on to the action. These are shallow and blacked inside to contrast with the polished bolt body.
The barrel is a stainless steel match grade famous German-made Lothar Walther (same as A.I )


We tried Nimrod in 2 calibres (.300 Win Mag and .308 Win), the 300 Win Mag had an AX AICS chassis in NRA UK Century Range at a distance of 600 yards. First we needed to do special zeroing procedures in Zero Range using a specific HME target, because of 300 Win Mag Muzzle Energy to meet the range requirement (.338 calibre HME rifles were not allowed on any of the NRA UK ranges in Bisley due to Range Danger Area and Air Danger Height requirements, which exceed the available range safety template and air danger height).

We had one .308 in AT AICS and .300 Win Mag as mentioned in AX AICS chassis (which had a Canadian built two-stage trigger form Cadex Defence), we used Accu-Shot Atlas Bipod V8, the scope mounts were American Defense AD-DELTA 20 MOA 1 Piece Quick Detach Unimount (as Nimrod got a flat rail), the scope we was Athlon Ares BTR 4.5-27×50 APLR3 FFP IR MOA.
Apart from AICS chassis, Nimrod can slip into other aftermarket stocks due to the Remington 700 action underside profile, it can come in PSE composite stocks from Cork, Ireland and GRS rifle stocks from Hornindal, Norway.
