We need support with some guns

There are a lots of famous guns in progress for Gun Disassembly 2. We also look for interesting models not just for famous one.
But there is a problem for references of internal parts. So, please, if anyone could help us with the photos of internal parts for the following guns we would be very glad. Also we can support with a promocode for some weapons in Gun Disassembly 2.
So it is a good deal.
Here are the models we need references for:
