Stock BoomCo Spring (For Double/Triple Spring Mods)
NOTES FROM LUKE: The Stock BoomCo Spring is one that I use a lot. These are left over stock springs after mods that can be doubled or tripled up in a BoomCo M6 or Farshot. Two of them provides a nice upgrade, while retaining a relatively easy prime compared to a K26 spring.
FEATURES: -Inexpensive upgrade -Stock spring recycled after mods
