"Modelgun Club" on Youtube?

Ok, I'm not sure if this has already been posted somewhere, and I'm also not sure if this actually IS a "Modelgun Club", but well... it sure looks like one
Many people showing their modelguns, obviously most of them custom jobs, many of them jamming, but more or less all of them very interesting:
tec9mac10's Youtube channel

Also, I'm pretty sure, it's Tanio Koba in the linked video firing that MP5A4 modelgun.

If you don't know this channel yet, check all the other videos, lots of modelgun fun

Hi Pydracor,

Nice find thanks for the link.
I'm pretty sure these clips are of the annual "All Japan Blowback" competition/convention. There are usually several one-off custom built modelguns that the contributors bring along to show.
The MP5 is indeed being fired by Tanio Kobayashi. Several individual video clips have appeared here in the past, it's good to have a link now to http://www.fvpd-guns.com/blowback.html also. There are some talented custom builders over there aren't there
