As you're asking for more than a grand for this, don't you think it would be worth itemising the upgrades instead of using vague language like "fully upgraded"?
Is the trigger box designed as single-shot only or has it been modded from one that has both single-shot and full-auto?
What inner barrel and hop bucking are being used?
What brand and model are the sight and magnifier?
You don't need to give the works of Milton but details won't go amiss. The inventory in the third image is a start but you really should be more transparent as the seller to inspire confidence in what you're selling.
