Griffon

1.4 No separating edges:
- Unlike other synthetic stocks, the asdm stock no separating edges on the outer contour to see or even feel. This is because our shaft is manufactured from a single piece. With traditional plastic manufacturing, this is not possible due to the manufacturing process.

Gap size

1.6 Weight:
- Despite the integrated comb adjustment, the complete asdm stock (including all stock screws) is lightweight (approx. 930g-970g).
1.7 Stability:
- Through an inlay process developed and patented by asdm, the shaft system achieves exceptional stability, which allows for its use all commercially available industrial Laboratories Even large calibers are allowed!
- The material
The material from which our products are manufactured is a high-strength plastic specially developed for asdm.
30% carbon fiber contentThis makes our hafting very
Stable, yet lightweight!
1.8 Strap attachment:
- We use the Ø9.5mm Phush&Go system to attach the rifle sling/strap, allowing us to flexibly meet customer requirements. This means there is a choice between two options.
- Snap button variant 1
- Stud adapter variant 2

asdm integrates 3 mounting sockets as standard.
- 1x Forend
- 2x buttstock bottom, and top (stock back)
- We recommend the #PG.VA1 variant, as it is easier to handle and allows for flexible alignment of the sling swivels in the stock without the use of tools.
2. Haptics
2.1 Haptic fore-end:
- We place the greatest importance on the
ergonomics Our stock design is therefore based on the forend's design, which is equipped with a grip strip and thus suitable for
Equally suitable for left- and right-handed users.


2.2 Haptic buttstock:
- The buttstock is generally equipped with a Pistol grip Designed specifically because only this design ensures an ergonomic, relaxed, and more sustainable posture when firing. This is based on our many years of experience and is the core of our product philosophy.
- The pistol grip is shaped in such a way that it for smaller and larger hands a very good and grippy hold offers this because it is available in sizes S, M, L and XL, suitable for every shooter.
- The geometry of the pistol grip is modeled on the natural shape of the hand and therefore fits ergonomically into the shooter's hand.
- Compare for yourself between the manufacturer's hole pattern and the... asdm holein the following two images. In this example, the archer has the Hand size L !
- Which shaft allows the hand to properly and securely grip the handle?


3. Adjustable comb / cheek piece

3.1 Attack:
- Since hunting rifles are generally no longer guided exclusively via open sights, but rather via a telescopic sight or red dot sight, the cheekpiece of a traditional stock is located in a much too low position to position the weapon safely and, in the truest sense of the word, efficiently and quickly. The stock's back is positioned in the area of the upper jaw and therefore does not offer a good fixed point.
- We have the solution for an optimal attack.
(see gallery: attack in comparison).

The solution:
- An individually adjustable stock back from asdm.
- Our approach is to position the cheekpiece at the only supposedly sensible fixed point in the lateral half of the face, the cheekbone!
- This is also clearly evident in the Video, quick repetition.
- Our goal was to... full function in the Buttstock to integrate, so that the design still retains a traditional and elegantly slim appearance.
- In the buttstock no KickStop to be installed the one for that The space required was used to accommodate the mechanism for the adjustable comb.
Steering:
- The extension function is enabled by a
control knob
actuated on the underside of the shaft.
Damping:
- The cheek piece is extended
low noise, because we have integrated a mechanism that dampens the lifting movement.
- The cheek piece is extended
low noise, because we have integrated a mechanism that dampens the lifting movement.
3.2 Rapid Repetition:
- The fast and reliable repeating is absolutely The raised stock crown ensures that the target remains in focus!
- It is not necessary to remove the thumb from the grip recess. This allows the trigger position to be resumed quickly and safely! (see video below)
3.3 How does it work?
- The height stop, which can be individually adjusted to the desired extension height, is also set with repeatable accuracy using this control knob. It is possible to adjust the shaft back in 2.5mm increments individually to adapt flexibly to the ergonomic requirements of the shooter and the respective hunting situation (e.g. stand hunting, driven hunt, stalking, mountain hunting, tracking or long range as well as with the different aiming devices from open sights to the large telescopic sight).
- The max. Extension height amounts 35mm.
- To fully extend the shaft back, the control button is pressed in completely.
- If the button is held in the fully depressed position, a stop unit is simultaneously locked in place.
- Now the shaft can be pushed to the desired height.
- When the control knob is released, the stock backstop is positioned and you have set the extension height to your desired level. This position will remain until it is readjusted.
- Now the control button can only be pressed halfway in, in order to then fully insert the stock back.
- Now, if you press the control button only slightly again, the shaft back will extend automatically only to the position you have preset (memory function).
- The extended stock comb is secured by a sophisticated mechanism. absolutely recoil-proof held in position!
(see video below)
4. Pistol grip:
4.1 Four different piston handle sizes: S, M, L, XL
- There's a good reason why clothing doesn't only come in size M, or shoes in size 42.
- We all have different sized hands, some small and delicate, others large and strong!
- A weapon must be held in a relaxed and secure position so that one can wait longer for the right moment to make a good hit.
- asdm offers the right stock geometry for everyone, and therefore also the right piston grip size!
- Four different sized handles are available: S, M, L and XL.
- We would also like to mention the Ladies were intended, who, in our experience, will primarily find the right size in sizes S and up to a maximum of M!

4.2 Size chart Handle sizes:
- To Decision aid do we have a Size chart developed to give you guidance on which size is right for you.
- We recommend: If your measured size is exactly at the upper limit of a handle size, please choose the next larger size.
- You should always consider whether you will primarily be shooting or assuming the firing position with or without gloves.

Compare for yourself:
- We will attempt to illustrate the difference to the usual shanking in a visual comparison. (see button below), of course it is even more convincing if you hold the asdm shaft in your own hands.
- Make an appointment with us; we would be happy to advise you at our premises.
5. Stock set:
- The buttstock is angled to the side to facilitate a more ergonomic shoulder position, thus relieving strain on the shooter's neck. This ensures optimal shoulder alignment.


- The pistol grip is angled outwards to accommodate a more natural hand position in the firing position.

What is the barrel diameter of your weapon?
Since a barrel typically has a tapered outer diameter and may have been shortened, please measure the barrel at the end of the forend for reference and select the appropriate index designation in your order! (See the following example: measured value is 17.56 mm, the appropriate index is #DM17 in the order form)
