Theorized, Designed, and created in the BCFF Ecosystem - we bring you an upgraded plunger for the Zius BK1S and BK2S. SLS printed in Nylon by a local supplier.
Ported, with a speed seal - seals majority all the way down the plunger tube. Testing shows likely no real FPS gains, possibly a minimal 3-5fps change. But the consistency of shots is significantly improved - those random 20-30fps below shots on brand new darts mostly disappear.
This has been our starting point for improvement, pretty much the first step needed to push the performance on the BK1S/BK2S blaster.
Comes ready to install, with a 30x2mm O-ring, and TPU shock absorber.
