This listing is for 2 springs.

These springs are designed for low power Air Rifle.

The spring is made from softer material, designed around 7-12 ft/p( foot per pound ).

These springs get compressed by 14 %, after around 20 times used you will get condensity power. 

 During the final tempering stage, they are coated with a zinc finish.

After springs get compressed by 14 % they do not lose any more power and are settled when left cocked for long periods.

Please note: 

For the installation of springs into Air Rifles it is sometimes necessary to remove coils by way of grinding or cutting the spring. This is normal and should be taken into consideration before fitting. Please test your airgun with a chronograph to ensure you remain below the UK power limit.
