The Maxx Model M4E is a high-performance CNC-machined hop-up chamber specifically designed for the M4/M16 AEG platform. Developed as an evolution of the industry-leading Maxx chambers, the M4E utilizes a rotary dial system for precise and stable hop-up adjustments. Machined from a solid block of aircraft-grade 6061 aluminum, this unit provides a rigid platform that significantly improves the air seal between the nozzle and the bucking. The M4E is engineered with strict tolerances to eliminate the play found in factory plastic chambers, resulting in improved shot-to-shot consistency and increased muzzle velocity.

Technical Specifications:

  • Precision Manufacturing: CNC-milled from a single block of 6061 aircraft-grade aluminum for maximum durability and alignment.
  • Rotary Adjustment System: Features a precision rotary dial for minute, stepless increments of hop-up pressure.
  • Enhanced Air Seal: Designed to provide a near-perfect airtight seal, often resulting in a 10–30 FPS increase over stock units.
  • BB Latching System: Integrated with a spring-loaded latching arm to prevent BBs from dropping out during magazine changes (manually releasable).
  • Nozzle Compatibility: Optimized for a wide range of air nozzle lengths from 21.00mm to 21.25mm.
  • Stability Enhancements: Equipped with a CNC Delrin C-clip and brass side wings to lock the inner barrel and chamber securely into the gearbox.
  • Interchangeable Tensioners: Includes two CNC-machined tensioners (standard and concave) for full compatibility with R-hop, Flat-hop, and standard buckings.
  • V2 Compatibility: Engineered for standard Tokyo Marui-spec V2 gearboxes found in M4, M16, and AR15 series rifles.
