Arcturus is a respected name in the airsoft world, known for engineering precision, innovation, and an extensive lineup of high-performance AEGs. Whether you're a beginner or a seasoned player, Arcturus has a series tailored to your playstyle and performance expectations. In this article, we compare five key product series from Arcturus: ME, SE, FE, PE, and C.A.T, each designed with different user needs in mind.

ME Series (MOSFET Enhanced)

The ME Series is the perfect entry point for new players who seek durability and reliability without diving deep into advanced electronic systems. ME replicas feature a mechanical microswitch trigger system, combined with an inline MOSFET to improve battery compatibility (up to 11.1V LiPo) and lifespan. These models offer a tactile trigger response and are equipped with reinforced polymer receivers, hybrid gearboxes, and rotary hop-up units.

SE Series (Standard Enhanced)

Aimed at beginners but with a touch of high-end features, the SE Series includes an ETU (Electronic Trigger Unit) for programmable firing modes, improved trigger response, and ROF management. SE replicas come with 23T torqued-up motors, 18:1 gear sets, quick spring change systems, and are 11.1V LiPo-ready. Available in various lengths, SE rifles also come as Starter Packs including a battery and charger, ideal for newcomers.

FE Series (Feature Enhanced)

FE Series guns bring a significant step-up in customization and programming. The ETU system allows players to adjust trigger sensitivity, active braking, and fire modes such as binary or burst. With CNC aluminum handguards, high-strength polymer receivers, and ambidextrous controls, the FE rifles are ideal for advanced users wanting flexibility, performance, and a competitive edge. These replicas are also fully compatible with aftermarket GATE ETUs.

PE Series (Performance Enhanced)

Built for elite players, the PE Series features top-tier internals such as 13:1 CNC gear sets, high-torque Neodymium motors (21T/23T), and programmable fire modes. These rifles include adaptive algorithms for progressive triggers, ROF deduction, low battery warning systems, and diagnostic capabilities. With CNC machined parts and high-quality materials, PE models represent Arcturus' most advanced AEGs, designed for professionals and high-demand scenarios.

C.A.T. Series (Custom Adaptive Tactical)

The C.A.T. line is Arcturus’ most modular and competition-focused offering. Designed for indoor and CQB play, it features a split Centaur gearbox, FE-level ETU system, modular magwells (AR, AK, PCC compatible), and foldable stocks. The C.A.T. Versatile series emphasizes customization with M-LOK handguards, ambidextrous controls, and multiple lengths and calibers available. These are truly player-configurable rifles for those who want maximum personalization and innovation.

Which Series Should You Choose?

• Experienced Players: Consider the FE Series for better control and features.
• Professional or Competitive Users: Opt for the PE or C.A.T. Series to access the most advanced tuning, programmability, and modularity.

No matter the choice, Arcturus offers performance and quality across all tiers, making it a top choice for any airsoft enthusiast.
