I was looking for an AR-7 too. I needed a small, take-down rifle to fit behind the seat of my truck. Also it would have to go in the trunk of my Honda Pacific Coast.
I chose the Marlin "Papoose". It's all stainless steel with a synthetic stock. I love it. It doesn't break down and fit in it's own stock, but fits in a cordura carrying case. 3.25 pounds. I think the Papoose is the best.
