Specna Arms MK18 HPA (Polarstar F2) Set

Selling my absolute compromise-free MK18 HPA project based on a lightweight and highly maneuverable Specna Arms polymer body (FLEX series). If you are looking for a setup that is feather-light to handle but delivers maximum performance and brutal trigger response thanks to high-end internals, this is the one.

The system runs buttery smooth, feeds flawlessly, and is completely skirmish-ready.

The Inner Values (High-End Upgrades):
• Engine: Polarstar F2 HPA Engine (the absolute gold standard for consistency and advanced tuning)

• Hop-Up Unit: MAXX Model Hop-Up Chamber (for laser-accurate adjustments)

• Trigger: MAXX Model Tuning Trigger (fully adjustable for an incredibly short pull and crisp hair-trigger response)

• Inner Barrel: High-quality stainless steel tuning barrel

Externals & Accessories:
• Body: Lightweight, durable nylon-reinforced polymer body—ideal for long game days without getting tired arms.

• Suppressor: QD (Quick Detachable) Suppressor—snaps on and off in seconds.

• Optic: EOTech Holo Replica 

• Stock: Original Magpul Stock for perfect ergonomics and comfort.

Massive PTS Magazine Package (10 Mags Total!):

Condition:
Well-maintained and regularly serviced. The HPA engine runs flawlessly. The body shows typical, minor cosmetic signs of use from gameplay, but nothing affecting performance.
