We from croatian military forum get contacted by a real "private" owner of a VHS that posted a thread with some extremely interesting pics of the rifle's interior mechanism.
I've so send it the link to VHS patent and so having both the blueprints than the real thing available we were able to clarify more details about VHS's more interesting features.
Considering however than pictures also are a private proprierty i'll post here only a link to the said thread:
HS VHS-K bullpup assault rifle
On It you will see some treats like:
How a modern tappet system work,
a double fusion match grade barrel on a service rifle,
the simplest way to get a forced air cooling on a automatic rifle (tappet system has a lot to do with that).
recoil dampening system
Thanks to aquatrax for sharing those info with us...
