Top takeaways

  1. The Green spring is optimal for A1/A2 fixed stock rifles with rifle length receiver extensions and is also compatible with VLTOR A5 buffer tubes.
  2. Designed for use with .223, 5.56, and similar calibers; may also work with heavier calibers in rifles with 20”+ barrels when paired with an H2 or H3 buffer.
  3. For over gassed heavier caliber rifles, the Red or Orange carbine springs with a standard carbine buffer and spacer are recommended for proper function.
