This suggestion is probably one of the top of unrealistic suggestions... And when you said 'is it more unrealistic than an as50 magically spawning somewhere' Yes it is. Cause that as50 has a history to why it got there.. A sniper could've gone to that spot pre-apocalypse, and died, leaving the as50 to sit there.. Or its in a barrack, and a marine left his weapon in the heat of the moment. There's no reason to make ammo or whatever to grow, Since there are so many more loot spawns coming to the standalone that if it would be like the way you suggest, people would go camp a single car-wreck and just wait for that makarov to turn into a m4a1 SD or something like that. There, Made my case.
