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
SPECS:
-Stainless steel spring
-3.6"
