I bought one of these a couple of weeks ago and really like it. The manual only says to hit it with a toothbrush and a few drops of oil and that further disassembly will void the warranty. Well, I've put about 300 rounds through it and it doesn't seem to get very dirty, but I've never owned a firearm that didn't need a thourough cleaning sooner or later, usually sooner. I've done Bing-searchs for disassembly videos, but they don't seem to exist.
Can anybody provide a link to a video or instructions?
One will eventually show up on Youtube. I've seen them for the Umarex Colt M4 complete breakdown and it's similarly difficult.
is htis what you looking for

It doesn't show how to remove and disassemble the bolt carrier group. I guess it's isn't necessary if hosed-down and flushed-out with Gunscrubber.
