This should be like clash of clans, you sell something e.g. Decorations and you get like 10% back. So if there was to be a gun refund system, it should only give a small offerable amount, making players convinced to stick with their gun. However, instead of 75% back in under 24 hours, why not have a test area where you can test it for 5 minutes. Afterwards, you'll decide. I've been reading some replies and i fuzed them together.
