Latest video demo from RA-Tech conducting ballistic tests with the KSC M4A1 and WE M16A1 gas blowback rifles in an indoor environment at a range of 30 metres in their original conditions. It seems that the WE M16 has better groupings than the KSC M4A1, but then, it has a longer barrel. It would be nice if they compare these against versions that use the RA-Tech upgrade parts. Watch the video below to judge for yourself.
