3 Rapax springs of your choice + bolt knob
When you place an order, write in note what spring strength you would like to get and you will get those + tough PETG 3d printed bolt knob, to make your SRS or Tac41 replica looks even more cool then it is.
7 springs of choice: Light Pull 2+, 2.8J, 3+, Hulk and RMS 2+, RMS 3+, RMS 4+, you can combine if you want.
Springs are 13mm outer diameter, so they fit SRS/Tac41/SSG10/24/96 and many more.
Rapax handmade springs – made in Europe to give you the best and most silent results for your sniper replica.
If the Rapax spring shoots too hot for your field, you can cut some coils without damaging the spring integrity as long as it is done properly.
The first thing you will notice is a lighter pull compared to standard springs. In short: less effort for more joule. For example, Silverback M140 and Rapax 2+J spring need similar pull strength but the Rapax 2+J spring gives more FPS/Joule in comparison.
All our springs are always the same length (depending of spring strength), use the same material, have the same number of coils, ect.
Spring wire used for Rapax springs production is of the highest quality spring wire, ensuring a prolonged period of usage compared to other springs.
Tempering of these springs is made in a way to guarantee a long lifetime and very small FPS/Joule loss over time.
Springs are made in tight tolerances regarding diameter, they prevent the “twang” sound in airsoft sniper replicas.
