"ION" Winter 85% Recoil Spring for VFC M4 / 416 GBBR Waldo Dynamics® (WD-VFC-WRS)

BRAND WALDO DYNAMICS®

The "ION" Winter Recoil Spring 85% by WALDO DYNAMICS® is designed to improve gas efficiency, smoothness, and reliability for VFC 416 and M4 GBBR platforms all year round.

Featuring an 85% strength rating, this recoil spring delivers the perfect balance between:

• efficiency
• responsiveness
• smooth cycling
• cold-weather reliability

The reduced spring tension improves gas efficiency and allows the rifle to operate more consistently in colder environments and winter conditions.

Despite the lighter tension, the spring still retains a crisp and realistic recoil feel, keeping the rifle responsive even during fast-paced gameplay.

The special blue friction-reducing coating improves cycling smoothness while making the spring easy to identify from other models.
