Airsoft Taiwan have uploaded a new video that continues the comparison between the GHK5 G5 GBB and the RA-Tech Custom G5 GBB in terms of accuracy. The tests are done with 0.40 BBs, powered by Green Gas, at distances of 30 metres and 40 metres. The Customised G5 is more accurate than the default configuration, but what the test impressed us is the sound of the G5 being fired as captured by the camera's built-in mic.
