The mod is excellent, but I think it would be better if the ejected shell models and tracers were more realistic. Also, the rounds shown inside the magazine during the reload animation are white instead of brass colored. The magazine ejection, magazine insertion, and bolt release sound effects are a bit too quiet as well. Finally, there is an issue where the three-round burst sound effect plays when firing the remaining two rounds after firing one round on burst mode or when you fire the last round on burst mode after firing two rounds. Besides that, this mod is great.
