It's Thailand versus Taiwan this time for CRW-Airsoft as he compares two airsoft guns made by SERS (Thailand) and GHK (Taiwan). The guns are the SERS AK104 AEG and the GHK AK105 which Eddie says are both of steel construction with the SERS being the heavier one. He also noticed that SERS is more realistic in design as compared to the GHK one. Find out more how both of these airsoft manufacturers make their guns in the video below.
