Well Pro WG13 Series Gas Blowback Airsoft M4 Full Polymer Rifle - (Black)
The Well Pro WG13 Series Gas Blowback Airsoft M4 Full Polymer Rifle Black is engineered as a lightweight, efficient GBB platform built around the WELL PRO operating system and a pre installed tunable NPAS nozzle. This combination supports consistent gas efficiency, smooth cycling, and adjustable velocity typically ranging from about 340 to 400 FPS with 0.20g BBs. The full polymer and nylon fiber receiver construction reduces overall weight while maintaining structural rigidity, creating a balanced rifle suited for extended skirmish or training use. Ambidextrous controls including dual selector, dual sided magazine release, and dual sided bolt catch enhance manipulation speed and realism for both left and right handed users. An externally adjustable hop up system allows precise trajectory tuning, while the 6.02mm inner barrel supports stable shot consistency. Internally, CNC machined metal components and MIM steel parts with QPQ finishing improve wear resistance, reinforced by a CNC steel plate fire control assembly for long term durability under gas blowback forces.
Offered in both long and short configurations, the WG13 adapts to different play environments with outer barrel lengths of 13.03 inches or 9.88 inches and overall lengths extending to 34.06 inches or 30.91 inches respectively. Standard 14mm CCW barrel threading supports common airsoft muzzle devices and tracer units, enabling further customization. The 30 round gas magazine capacity maintains realistic GBBR operation, while the lightweight 2.6 to 2.8kg build keeps the rifle agile during movement and transitions. Players searching for a gas blowback M4, polymer airsoft rifle, or adjustable NPAS GBB platform will find the Well Pro WG13 Series a versatile foundation for modern airsoft rifle builds. Its tactical black finish and compatibility with WG13 accessories and components make it a cohesive choice for field or CQB loadouts focused on realism, efficiency, and modular customization.
