Oh yeah that's another thing. While "AK-47" is used to refer to all AK's generically, strictly speaking it refers only to the first generation AK with the milled steel receiver. That was replaced fairly quickly by the AKM which used a pressed sheet metal receiver. This was lighter, cheaper and simpler to produce and less prone to breaking. If you look just above the magazine on your golden gun >>42133980
you'll notice a little lozenge shaped dimple. Those help to hold the magazine in place. A proper AK-47 with a milled receiver has a broad rectangular section milled out of it in the same place instead see here: >>42126566
(Also in video below).
Now to make things a bit more confusing Romanian AK's like my AES-10:>>42133985
don't have dimples, instead they spot-weld sheet metal tabs inside to hold the magazine. Also, the AES-10 is an RPK built on an AKM receiver. The AKM reciever is 1mm thick, while the RPK receiver is 1.2mm thick, making it a bit more rigid. If you watch an AK firing in slow motion it is pretty amazing how much they flex under recoil:Inside the AK-47
And all that flexing has a detrimental effect on accuracy which is further magnified by the longer barrel.
I had a pimped-out MP-7 in Wildlands on my old PS4 I think it had like, a blue and purple digicam pattern on it or something. I pretty much exclusively used the M110 and the Mk.48 in that game though. I started a new game of that the other day but quickly lost interest because I just didn't feel like spending 2 or 3 hours flying all over Bolivia collecting all the good gear and skill points before I actually started playing the game proper.
