Having weapon malfunctions that need to be cleared would be nice, however not on properly maintained weapons (since properly maintained quality weapons and quality ammo rarely malfunction in real life). But only on poorly cared for weapons, which leads me to my next suggestion... Cleaning kits for rifle maintenance would be nice also. If possible, the rifle would stay in a constant state of excellent condition unless exposed to rain or is fired. Then it would need to be cleaned or it would very slowly deteriorate, causing it to jam more frequently. Cleaning kits could be a tool belt item. Therefore people who have yet to find it would think twice about taking their brand new AKM and firing it for mindless murdering on the coast and might even think twice about using it to hunt for food. Instead, deciding to forage the grocery for beans and saving the weapon for a truely needful self defense situation, at least until the cleaning kit is found. Also, I would like to see interchangable optics, so you find the optical sights separate from the rifle. I can put a red dot or a ACOG on my M4 with a flat top receiver, so I should be able to swap them around in the game. That way I could have an M4 with a red dot for city runs, but carry a ACOG for long ranges and switch them out if I need more reach.
