Feinwerkbau 800 X Benchrest Walnut

The Feinwerkbau 800 X Benchrest Walnut is a high-end competition air rifle with lightweight aluminium stock, featuring all the quality components that one should expect on a Feinwerkbau precision rifle. An overview:

Stock

• Universal (left/right)
• Aluminium
• Adjustable wooden grip (length, offset, angle and rotation)
• Adjustable wooden support bar (tiltable 13 degrees)
• Adjustable moulded cheek rest (height, tilt and angle)
• Adjustable butt plate (height, angle, tilt, length)
• Butt plate features multi-adjustable support segments
• Adjustable butt stock offset
• Length of pull: 285-343 mm
• Stock length: 745-795 mm
• Accessory rail in fore end

The stock of the Feinwerkbau 800 X Benchrest Walnut is universally designed for both left hand and right hand use. Its butt part can be adjusted in height, using convenient indication markers. Two pivot points provide the option to swivel the frame to create an offset.  

And the butt plate is adjustable in every way, and the support segments can be adjusted in height, sideways position, angle and rotation. They can even be split and adjusted individually. Length of the stock and height of the check support can both be quickly adjusted with lockable adjustment wheels.

Trigger

• Multi-adjustable trigger blade
• Two stages
• Trigger weight adjustable (both stages), 30-90 and 60-150 grammes
• Direct trigger (no first stage)
• Adjustable for left- and right hand use
• Dry firing possible

The trigger of the Feinwerkbau 800 X Benchrest Walnut is adjustable in many ways. The blade can be adjusted for any finger length (27 mm) with a rail system, featuring two rails to cater for left- and right hand use. The trigger blade pin can be reversed and the blade itself can be rotated upside down with the long side down.

Both stages can separately be adjusted for trigger weight, while it’s also possible to shorten the first stage in such a way, that it’s effectively gone, leaving just the second stage for a direct trigger.

Barrel

• Calibre: 4,5 mm (.177”)
• Barrel length: 425 mm
• Barrel diameter: 15 mm
• Aluminium barrel sleeve
• Barrel sleeve diameter: 19,7 mm
• Barrel sleeve length: 585 mm

Feinwerkbau Absorber

The patented Feinwerkbau Absorber is designed to dampen the recoil to the absolute minimum. To create a perfect balance with the ammunition used, the absorber can be adjusted with a screw that should be rotated in turns of 30 degrees, which is comparable with 5 minutes on a clock face.

By pulling back the cocking lever until resistance is felt, the right adjustment range can be found. The distance between barrel mouth and bolt should be between 12 and 17 mm. Is the measured distance shorter than 12 mm, the screw should be turned clockwise (right). Is the distance greater than 17 mm, the adjustment screw should be turned anti-clockwise. All, as mentioned, in tiny steps of 30 degrees. Depending on the used pellet, the perfect balance can be found in this adjustment zone.

Vario-sight

The Feinwerkbau Vario-sight system offers maximum adjustability to both the diopter as the front sight. They can be adjusted in height, distance and even sideways displacement is possible. The height adjustment is done in steps, while the length (distance) adjustment is stepless on rails. For sideways adjustment, there are different bolt holes available for use.

Diopter:

• Tiltable 10 degrees
• Adjustable elevation
• Adjustable windage
• 20 clicks adjustment range

The Feinwerkbau Match-diopter can be adjusted in all relevant areas. Both elevation and windage have a 20 click adjustment range, where one click corresponds with a change in point of impact of 0,2 mm at 10 metres (and a 950 mm sight length). The diopter can also be tilted left or right in a 10 degrees range.

Air reservoir

• Maximum fill pressure: 200 bar (2840 psi)
• With valve (so detachable when filled)
• Interchangeable
• Toolless (hand) change

The air reservoir can be filled to a maximum of 200 bar, using demoisturised compressed air. As the Feinwerkbau 800 X Benchrest Walnut air reservoir features a valve, it can be taken of when (partially) filled and you can bring (optional) filled cylinders for a quick change.

No tools are needed to change the air reservoir. The system is designed to be mounted by hand. As the O-ring seals radially (on the outer circumference) and doesn’t rely on clamping, here’s no need to tighten the cylinder with force. Tightening with force doesn’t have any effect on the air seal, but could make unscrewing the reservoir harder or wear the fine thread.

Other features of the Feinwerkbau 800 X Benchrest Walnut:

• Fully reversible (including cocking lever) for left hand use
• Total height: 220-320 mm
• Sight height from centre of barrel: 27 (40-60) mm
