One issue I'm having is the assembly/disassembly is often arbitrarily specific. I understand taking out the magazine to emphasize safety, but after that, often times it's clear that parts could come out or off, but you're not allowed to because the game requires a specific sequence. The other problem is the game forcing you to click a specific part of a piece. Two pieces will be assembled together, but clicking one piece will assemble it, but clicking the other is invalid. I know I failed sniper achievements because on some pistols, you take apart the trigger assembly, but if you click on the trigger itself, it doesn't count. You have to click on the bar connected to the trigger. Others are things like taking springs off and having to click on the end of a rod to take the spring off, not the spring itself. It can make it a guessing game. You know which parts are supposed to go together, you just don't know which area the game wants you to click to do it.
