This CRBN M4 ESG build takes the guesswork out of competitive airsoft builds for the minimalist player who doesn't need attachments - it's everything you need to put BBs ropes down range. Sporting the top-of-the-line Polarstar Fusion Engine and a Polarstar Micro Reg Gen2 regulator, CRBN M4 is the lightest build ever made for competition. The Monk ESG brings both ergonomics and style, while the AirTac Customs Ultra-light CRBN upper receiver allows for swift handling and a clear line of sight. 

Stylistic Carbon Fiber trim has been applied to the hopup to complete the aesthetic of CRBN, and CRBN comes with a special Carbon fiber magazine.

Additionally, this build comes with:

  • Custom CRBN Midcap Magazine
  • MAXX Black Tunable Trigger
  • MAXX CRBN CNC Hopup Unit
  • Prometheus Tightbore Barrel
  • Maple Leaf Super Macaron Bucking
  • Durable Polymer G&G body
  • Amped Custom Micro-LiPo
  • Heavy-Duty Gun Case
  • Customized 3D endcap

The rate of fire and FPS can be adjusted to adhere to field requirements, and the included Polarstar FCU allows for programmable burst and auto modes. The MAXX model trigger is tuned for an extremely fast trigger response and crisp actuation.

180-DAY WARRANTY - For peace of mind, all AirTac Custom builds come with 180 days of warranty from the time they leave our shop.
