PRODUCT DESCRIPTION:
The subject of the auction is a complete ABSOLUTE TUNING for the Gamo Shadow 640 air rifle.
This is the most powerful tuning kit that you can physically fit into this model!
A set with two springs
With this set your air gun will reach Vo 360 m / s for 0.42g shots
This energy can only be achieved with two independent springs.
Power increase by 60% compared to one 3.6mm spring!!!
A double spring fills the entire piston chamber, which is a solution that despite being expensive was used in the 80’s in the best Olympic air rifles, i.e. DIANA 75
THE SET CONSISTS OF
- main tuning spring
- left-handed internal spring 2mm
- special metal guide ( all hardened steel, nitrided! )
- piston seal
- gasket on the barrel
- lubricant for moving parts
- special non-flammable oil for the piston
- instruction manual
FREQUENTLY ASKED QUESTIONS AND ANSWERS
- Can I handle the assembly?
Yes, replacing the springs is relatively simple, it does not require special tools, every adult person should not have problems with it, and in case of doubt you can always call us.
- Does the use of a double spring cause a buzzing noise?
No, the springs are adjusted in such a way that their use eliminates any vibrations (even if they are not greased!)
- Doesn’t such reinforcement cause rapid wear of the air gun?
No, air guns sold on the Polish market are in the version up to 17J, however, their factory settings can be much stronger. We have been successfully selling sets for about 9 years.
- Won’t the two springs get jammed?
No, springs will never wedge because one is right and the other is left-handed.
- Will the use of a double spring increase the air rifle’s recoil?
Yes, the recoil will increase slightly.
- Won’t the set affect accuracy?
No, the set does not affect the accuracy of the air gun.
- Is there anything stronger than this set?
No, the springs fill the entire piston chamber and there is no possibility of mounting larger ones.
- Do I need additional washers for springs, plugs, other elements when using the set?
No, the springs in the set are lined up so there is no such need, the use of additional elements may cause the trigger not to “snap”.
- The manufacturer wrote that the air gun reaches, for example, 300m / s, it’s not much less than with the set, is it worth buying tuning then?
Yes, the manufacturer gives the initial target speed; it does not take into account the limit in Poland17J which equals about 260m / s.
- I am going to buy a GAS RAM (gas spring) or is it worth buying a tuning kit instead?
Yes, GAS RAM always gives you energy up to 17J or around 260m / s. GAS RAM is not “eternal” with time, the air goes down or it breaks down. Good GAS RAM is the expense of a very good air gun, GAS RAM causes rapid damage to the body, and in contrast to the traditional spring, it gives energy away point-by-point.
- How “vital” is the set?
The oteva internal spring practically does not wear, only the main spring is subject to wear but it can be purchased in the future. The set, even with the outworn main spring, is much stronger than with one new spring.
- Must the gaskets be replaced?
No, they should be in stock; they are replaced only in the case of damage of the original ones.
- Can I buy the inner spring myself and insert it into my original spring?
No, the double spring requires a special guide, and besides it must be closely matched to the main spring.
- I have a slightly different model, will the set match?
If you have a different model, please contact us.
- The guide in the picture looks different than mine, will it fit?
Yes, the guide is selected for a specific model of an air rifle.
