Currently, you need to own the turret in order to select or view the augments of that turret, but for a free to play player, I tend to conserve my crystal so I don't just randomly buy turrets that I know I won't use for the next 12 years. But recently, Tanki Online has generously gave a bunch of container for every players, some of us lucky and got skins, and of course, augments. There was no other way to view the augments you got in the container other than owning the turret. Why can't we view the augments we got. We don't own the turret, but we own the augments. The turrets is cheap like 300 crystal, but I'd rather keep things simple, to just having the turrets I like in my garage. The augments is not cheap, about 5000 Tankoins per an augments. My suggestion was, you can click on any turrets augments icon (that you own or not own), and will be able to see which augments you have owned. Maybe this was an intentional feature, but either way, there is no downside of me know which augments I got. Or, you can view which augments you have owned in player profile, but I'd prefer it to be in garage. Why? If I see any augments that interested me, maybe I will invest into it. Maybe put 5 months worth of time into it or 1 year. Generally, I will spend my time in the garage and Tanki Wiki to read every description of everything in the game, so if I see any augments that is unique or fun to use, I will just buy it (crystal). I don't know how to implement this feature into the game, but just an idea that if future update can relate to, quality of life update.
