Pheas Airsoft breaks down a CYM CM.028 to review the internals in one of the Christmas video releases they did last month... "Surprise! Here is the fourth Christmas day surprise video as part of our old school xmas 2020 releases. These are all old videos (very old in some cases) which have never been worked into our release schedule! So thought we would be nice and drop them as 12 days of old school."
