Just bought this http://www.gunbroker.com/Auction/ViewItem.aspx?Item=237777450. I have a Zane Grey barrel but I've already built one of those. I have a regular 30/30 barrel and all the stuff I took off when I built the Zane Grey. Maybe cut down the regular barrel and make a shorty? Maybe put on the synthetic stocks? Leave the barrel long but do a short magazine?
