Upgrade spring for Elelctric guns (AEG).
- Springs are all "perfect" variable pitch, giving light compression and fast return. Some springs use a different "variable pitch", but that's just connect the some different pitchs.Those are difficult to compress and do not give the desired power.
- PDI uses silicon chrome steel to make the springs. Also, PDI can finely adjust the pitch using thissteel, so we can offer different power levels.
- PDI's Springs don't shrink! Generally,spring will shrink from 15mm to 20mm.We can control under 13mm-5mm.
Japanese manufacturers use the designation of the spring in the percent. The spring 100% has energy 0,8 J with 0,20g - it is cca 90m/s. This spring is M110.
