COMING SOON! WHAT IS THE DIFFERENCE
BETWEEN A HK21/21EUG AND A HK21E?
Both are GREAT systems but have major differences. Due to the many calls we
receive on what the cost of a HK21E is, when what is actually being asked about is
the HK21(60's era) that is out there being sold and marked as a "21E". We trademarked our
Upgraded 21 as "21EUG" and are very clear to our clients that it is an upgraded
60's era 21and would never call it an "E". We have built and sold both over the
years. If your looking for a "21E" and it doesn't have a "E" swing down feed mechanism it is not even close.
But we have been spending so much time on the phone educating potential clients
that we felt if its explained on our site a educated decisions can be made on
either system. We do have a limited number of "21E" UBF's available, with HK
German "E" swing down feed mechs and bolt carriers. These can be converted to
.223 with the proper swing down feed mech, bolt head, locking piece and barrel
in a matter of minutes! To all our clients that have been patient on the backlog
of "21EUG" and "21UBF" builds we appreciate you. Almost up to date
and working on decent time frames.
