Zius BKS | BCFF Speed Seal Plunger

The BCFF Speed Seal Plunger is a precision upgrade part designed to optimise the performance of BK1 and BK2 springer blasters. Developed entirely within the BCFF Ecosystem, this plunger features a unique Speed Seal system that offers minimal drag during priming and a tight seal when firing — striking the perfect balance between smooth operation and consistent power.

Professionally SLS printed in nylon for maximum strength and durability, the plunger also includes three upgraded TPU bumpers to enhance rack tooth alignment for improved reliability.

Features:

• Designed, tested, and created in the BCFF Ecosystem
• SLS nylon printed in Canada for superior rigidity and wear resistance
• Speed Seal system for low friction when priming and positive air seal when firing
• Includes 3 additional TPU bumpers for optimal rack tooth alignment

Disclaimers:

• Due to moulding tolerance differences between BK1 and BK2 platforms, some post-processing may be required to ensure optimal fit and function
• When installing the blue TPU spacers, ensure proper hole alignment when gluing to maintain Speed Seal functionality
• Familiarity with hard-resetting BK1s/BK2s blasters is required for effective troubleshooting post-installation
