JJ Sport features an Airtac-based HPA build utilizing a G&G SRL M4 lower receiver. The internal configuration is centered around a Polarstar Fusion engine equipped with a purple poppet, purple nozzle, and a lightning banjo. Power is supplied by an Airtac 7.4v battery, while an Airtac regulator manages the air system.

The exterior assembly includes an Airtac aluminum HPA upper receiver in black, complemented by an Airtac Axis Speed QB grip. The build is accented with purple Airtac components, including the mag release and back plate cap. Black Airtac body pins secure the frame, and the firing mechanism is rounded out with an Airtac trigger.

For accuracy and utility, the setup incorporates a G&G/Laylax 6.01mm tightbore barrel housed within a black Airtac Maxx hop-up unit. The muzzle end features the G&G RT-F99 remote tracer unit to assist with low-light tracking.
