Jing Gong PM5K AEG – M4 Stock Tube

The Jing Gong PM5K AEG with M4 stock tube brings practicality to the classic PM5K platform. By adopting an M4-compatible stock tube, this build solves one of the PM5K’s traditional pain points: battery fitment. The rear-wired gearbox and standard stock tube mean you’ll have significantly more options when sourcing or upgrading your power system.

Key Features

• M4 stock tube – easier battery placement and sourcing than conventional PM5K designs
• Adjustable stock – comfortable cheek weld and length-of-pull customisation
• Rear wiring – simplifies internal upgrades and maintenance
• Compact form factor – ideal for CQB, urban milsim, and tight skirmish zones
• Reliable Jing Gong construction – solid platform for beginner-to-intermediate upgrades

Real-World Use Cases

This PM5K suits CQB environments where manoeuvrability matters more than long-range accuracy. The compact dimensions make it excellent for room-clearing drills in milsim events, whilst the adjustable stock ensures comfort for players of various builds. The M4 stock tube also means you can easily swap batteries between this and any M4 platform you might own.

Technical Specifications

• Model designation: 205t (M4 stock tube variant)
• Platform: M4 stock tube with PM5K receiver
• Stock: Adjustable

Compatibility & Upgrades

The M4 stock tube opens the door to standard-issue M4 battery options, dramatically expanding your choices. Look for 7.4V–11.1V LiPo batteries with deans or T-connector plugs sized to fit the stock. The rear-wired gearbox also makes internal upgrades straightforward if you later decide to enhance performance or durability.
