unload / remove the belt from the M240, M249 and you can fire a single round from those weapons. PKM is the only exception to the rule as this is correct mechanically.

I know its probably to much to ask for but could it be possible to tighten up the rear sights on most of the weapons like how ARMA 2 had it. most of the weapons in game have this unrealistically large and open rear sight, very noticeable with the PKM. it seems like a step back in comparison to the fidelity of other features in the game.
