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
SPECS: • Material: Stainless steel spring • Dimensions: 3.6" long
