Features

  • Designed to provide consistent gas flow regardless of the amount of contact between the loading nozzle and BB
  • Precision machined aluminum alloy bolt carrier
  • Parkerized style finish provides protection against wear and tear and adverse weather condtions
  • Designed to dramatically improve gas efficiency
  • More consistent gas use provides the user with a more consistent, higher FPS
In a vast improvement over the original Western Arms gas system, G&P developed the Negative Pressure Bolt carrier group for the G&P/Western Arms M4 series of GBBRs. Whereas the original WA system requires contact with the BB to open the valve plunger, the G&P negative pressure bolt provides a steady output of gas, regardless of the contact between the nozzle and the BB. Like all G&P gas blowback bolts, the G&P negative pressure bolts are machined from light and ruggedly durable aluminum alloy with a wide variety of finishes

Compatibility: G&P CNC "Bomber" Metal Body GBB rifles only
Material: Aluminum alloy, polymer

Manufacturer: G&P
