Maxx CNC Aluminum Hopup Chamber M4G (for Standard M4)

Maxx Model CNC Aluminum Hop-Up Chamber M4G (Standard AEG/HPA Series)

The Gold Standard for G-Style Performance.

The Maxx Model M4G is a high-performance rotary hop-up chamber specifically engineered for standard M4/M16 platforms. Built for the player who demands perfection, the "G" series is optimized to provide a rock-solid air seal and incredibly fine adjustment control, ensuring your BBs fly straighter, further, and more consistently than ever before.

Whether you are running a high-end AEG or a drop-in HPA engine (like a PolarStar or Jack), the M4G provides the rigid, precision-machined housing necessary to eliminate the variables that cause flyers.

Why the M4G Stands Out:

• Precision Rotary Adjustment: Move away from the old-school gear systems that reset themselves during play. The M4G features a high-torque rotary dial with micro-click numbering, allowing you to fine-tune your hop for different BB weights and lock it in place.

• Superior Air Seal: CNC-machined from a solid block of Aircraft Grade Aluminum to extremely tight tolerances. This reduces nozzle movement and ensures a consistent seal against the bucking, directly resulting in improved FPS consistency ($+/- 1\text{--}2$ FPS).

• Advanced BB Latching System: Tired of dropping 4-5 BBs every time you change a mag? The M4G features a spring-loaded latch that holds BBs inside the chamber, preventing waste and ensuring your first shot after a reload is always "hot."

• Optimized Feed Path: The internal feed tube is designed to reduce friction and eliminate jams, making it compatible with high-speed mid-caps and high-ROF (Rate of Fire) builds.

• Tracer & Sensor Ready: Like the rest of the Maxx family, the M4G is designed with ports for optional LED Tracer boards, allowing you to light up the night without needing a bulky muzzle attachment.

Technical Specifications:

• Material: CNC Machined 6061 Aluminum

• Compatibility: Most standard V2 M4/M16 AEG and HPA platforms (Tokyo Marui, VFC, G&G, etc.)

• Adjustment: Rotary Dial with Micro-Click numbering

• Included Nubs: Comes with multiple interchangeable nubs for Standard, Flat-Hop, and R-Hop setups.

The Verdict:

The Maxx M4G is the single best "quality of life" and performance upgrade you can give a standard M4. It transforms a basic hop-up system into a professional-grade tuning tool. If you want to out-range the competition and stop wasting BBs during reloads, the M4G is the answer.

In the box:

• 1 x CNC Aluminum Hop-Up Chamber M4G

• 2 x CNC Acrylic Side Covers

• 1 x CNC Brass Threaded Slot Pin

• 1 x Set of Hop-up Arms and Nubs (Standard & R-Hop)

Tech Tip: For the absolute best results with the M4G, ensure your nozzle length is properly matched (typically 21-21.5mm for standard M4s). We recommend a Maple Leaf 70° Macaron for an easy, high-performance pairing.
