Product Overview
Boost your VFC GBBRs performance year-round with the Waldo Dynamics Winter Hammer Spring, precision-engineered for the VFC AR and MCX GBBR platforms. Designed at 75% strength, this hammer spring delivers improved gas efficiency over the stock component but can still be used all year around.
Despite being a weaker hammer spring you can still use this in peak summer on your usual green gasses. Extensive testing in climates all over the world has found no issues with it's capabilities. This simple upgrade can be installed within 3 minutes.
Finished in a distinctive blue 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.
Compatible with:
- All VFC AR based GBBRs (KS1, BCM, URGI, XM series etc)
- VFC 416 GBBR
- APFG MCX GBBR
NOTE installing this spring can be quick and relatively easy, but does require knowledge for installation. See the video as a guide for installation.
