You asked, and Waldo Dynamics have provided; An icon in the recoil spring world for GBBRs

Sometimes you just want your GBBR to snap that little bit more, so Waldo decided to make you a spring just for that. Built at an estimated 140% strength, this gives quite a change in impulse when firing. If you were to pair this with a heavyweight buffer too you'd see a huge improvement in recoil. 

Finished in a distinctive purple coating, the finish not only reduces friction (giving you a butter smooth shooting experience) but it also helps you tell it apart from other springs you may have.

Key Features:

• Compatible with VFC/GHK/VT/WA Spec M4 GBBRs 
• 140% power rating for improved impulse and recoil potential
• Purple friction-reducing coating for smoother cycling, durability, and identification
• Retains snappy, responsive action across a wide temperature range
• Ideal for players running GBBRs who are looking to elevate their shooting experience

Trusted by techs and field-tested by serious players, the Waldo Dynamics "Ion" Recoil Spring range is your go-to upgrade for seasonal performance without compromise.

The end of the spring with the most coils is the side that receives the recoil buffer (as illustrated in the product photos). This product does not include a recoil buffer.
