Very light rifle, although I haven't fired it yet, and the version I handled was a civilian one, with only semiautomatic firing mode available (Brazil) Many games portray the rate-of-fire of this gun *wrongly* . It is very fast, much faster than you expect it to be, when using the full auto mode.
Although their animation is wrong and pushing the forward assist is not obligatory! When you load (first time) the weapon, you pull the charging handle. When you reload (freshly emptied magazine) you just press the bolt release button. Pushing the forward assist is optional, it is not part of the reload sequence.
