Maybe a mock suppressor could exist between the bottle suppressor and the real suppressor. Bottle suppressors would have low durability, mock suppressors medium durability, and real suppressors high durability. That way it fills a small progression gap 
Bottle suppressor → low durability (cheap, temporary)
Mock suppressor → medium durability (better but not perfect)
Real suppressor → high durability (best option)
Bottle suppressors should be the easiest to get, mock suppressors medium rarity, and real suppressors rare
