There should be a new shop in the lobby, which will "sell" you untradeable/unkeyable/etc weapons for coins. After 1, 7 or 30 days (Depending on how long you "Purchased" it for), the gun will be removed from your inventory. Basically, you could rent whatever gun you wanted. Wanna try out one of those Extinct guns? Just pay some bucks.
The only people who would disagree with this would be jealous fucks who just don't want others to try out new weapons. It'd basically be a large catalog of whatever guns you wanted to try out, or even possibly tiers. Maybe you could rent guns for Rubies too at a discount.
If you want to expand upon it, add new types of shards that you can use to "Customize" the gun you rent a little bit. Add a different trait, maybe try a suffix. Cost would multiply, but it'd be fun. Really, its just a feature to let people try out cool shit and have fun while wasting coins.
