Reign of Fire is an HPA M4 Airsoft rifle built for relentless speed and precision. Its Nexxus SA mechanical engine delivers ultra-fast response, semi and full-auto fire, and impressive air efficiency. The Roto Bucking-less Hop Up boosts consistency, seal, and range, while the X-Mold Pro-Bolt enhances performance for a hard-hitting, tournament-ready setup.

Nexxus SA HPA Engine
Mechlabs brings you the Nexxus series engine for the M4/AR15 platform. The Nexxus is a full mechanical engine capable of firing in semi-automatic and full automatic with flip of the selector. No need for batteries just hook up your HPA tank and you are ready to rock. It also boasts an ultra fast trigger pull and is very efficient on air up to 3000+ shots with a full 48/4500 tank. The Nexxus engine comes ready to attach to your external HPA regulator set up but if you'd like to run a shoulder stock tank we have a kit that has a regulator built in. Jump on board the HPA revolution with Mechlabs!

Roto Bucking-less Hop Up
MechLabs' patent-pending ROTO Bucking-Less Hop-Up Chamber redefines Airsoft hop-up performance by eliminating the traditional rubber bucking and replacing it with a precision-engineered contact system. Built for HPA and high-performance builds, it delivers greater durability, perfect alignment, improved air seal, and more consistent backspin, accuracy, and range shot after shot.

X-Mold Pro-Bolt
The X-Mold Bolt is engineered specifically for the X-Mod HPA engine, yet remains fully cross-tech compatible with the NEXXUS and ARC platforms - allowing existing users to benefit from the same advancements in air performance and efficiency.

Pro-Bolt Air Performance Enhancements:

• Reduced Air Consumption - Improved efficiency provides more shots per tank while maintaining consistent output.
• Optimized Burst Management - Lower air-volume demand during rapid fire makes the X-Mod more stable and compatible with lower-flow third-party regulators and tank presets.
• Adjustable Nozzle System - The nozzle can be precisely adjusted to fit perfectly within the hop-up chamber, improving grouping and output stability. At the same time, it synchronizes the internal air-cycle rate to deliver the optimal air volume for different nozzle lengths and configurations.
• Minimized Shot-Down Effect - Delivers smoother transitions between semi and full-auto fire, reducing FPS drop and maintaining accuracy across bursts.
