Double Bell 795 5.1 Hi Capa GBB Blowback unit disassembly

[ronnie villanueva]

Greetings! Can somebody help me? I was trying to disassemble my gbb pistol's blowback unit but I couldn't find any tutorial on the net that's the same brand and model with what I have. It seems that the blowback unit housing is locked by a fake firing pin (green arrow) and what it seems to be like a knocker valve (red arrow) being striked by the hammer. Now, that pin is spring loaded and hits a metal block (blue arrow) where a screw is screwed in. That's the only thing that what's being held the bbu to the slide. I already removed the 2 screws on top of the slide where the iron sight is. I tried pulling it up so that it will stay clear off the metal block but still gets snagged at the edge of the block, now it can't go any further. Is there anyone have any idea how to work around this? Thanks...
