EXCLUSIVE POSSESION
PDI SPRINGS have been selected by AIRSOFT PLAYER FOR A LONG TIME. We've already sold 300,000 pcs over.
Variable Pitch
Our 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.
Silicon Chrome Steel
We use silicon chrome steel to make the springs. Also, we can finely adjust the pitch using thissteel, so we can offer different power levels.
All Hand Made
Each spring may look different because our springs are individually made by skilled craftsman. Springs that provide the same power may be slightly longer or shorter.Our springs couldn't be made by machines because of our complete ly variable pitch.
Keep the Style
PDI's Springs don't shrink! Generally,spring will shrink from 15mm to 20mm.We can control under 13mm-5mm.
