Waldo Dynamics "Ion" 140% buffer spring for VFC M4/GHK M4/VT/WA M4

A 140% buffer spring . Using this spring alters the recoil impulse, making the recoil more pronounced and powerful. When combined with a heavier buffer, it provides a more realistic recoil effect.
The spring features a friction-reducing coating for smoother operation within the guide rod, whilst its purple colour allows for easy identification.
The ideal solution for players who want to make their GBBR even more realistic.
