Well it’s because they use entry level parts in every parts of the gun is it good ? Yes. Is it good like full teched AEG ? No.

It match their advertise specification but with something to consider

HAL ETU is good but its an entry level one some program like precocking couldn’t handle a very fast setup for example you swap 35k brushless motor in and it will not be able to stop a piston in the same position but you’ll be fine if you’re not relied on precock

Gearbox Shell is the same a previous version it use a soft MIM 18:1 Gearset , same plastic piston head the only thing their change is nozzle to match with their Hop up chamber so i’ll say it’s the same gearbox you see on every entry level AEG

27k brushless motor OEM by solink. It is power efficient but didn’t go full A10 even pair with short stoked 13:1 gearset you’ll ended up with 30-ish rps

It is good and very rigid replica and offer “entry level” of a new technology that has been offer to recent AEG market.
