NexxSpeed CNC Piston Head For Tokyo Marui TM Hi-Capa / 1911 GBBP

The CNC Aluminum Piston Head is machined with precise CNC tolerances from Aluminum and 2 O-rings for improvements in stability, durability and overall performance.

The piston head seals especially well and does not allow any gas to escape, making the nozzle work more smoothly.

With the O-ring on the screw fixes the gas leak problem.

FPS can increase from 10FPS - 20FPS compared to stock.

Note* This is for a stock TM BBU. Will not work with EDGE or Cow Cow BBU's.
