My attachments for my SG5-K keep de-spawning off of my gun every time I logout. Eg. Rail mounted hand grip with Universal flash light and Suppressor.
Side note. Compensator is installed when Suppressor is installed. Must install Suppressor first, then Compensator. Not the other way around. Haven’t tested to see if that might be the issue. Not sure if the Compensator and Suppressor are compatible. And if it’s just a glitch to attach those two components at once. FYI
