Madbull JP Rifle Conversion / barrel kit (looking for the shortest barrel piece)

[Dayton]

I'm looking for the shortest barrel piece out of a Madbull JP Barrel Kit.

It's this kit: http://www.airsoftgi.com/product_info.php?products_id=2816

I need the shortest piece out of that kit. If you have one of these and don't need the short one, I would love to buy it off you! I will come pick it up or pay for shipping.
