A comprehensive review by REAPERs Airsoft of the Arcturus/Umarex HK416A5 Version 2023 S-AEG (German-spec). What we know about this replica is that it has a durable aluminum body and steel parts. It has a reinforced gearbox with reliable internal parts and a quick spring change system. It also has an electric trigger that works well with Li-Po batteries and prevents contact damage. The nozzle, hop-up chamber and barrel are sealed and precise.

But still best to watch the video review below if REAPERs Airsoft agress with manufacturer-provided information or not:
