I was tempted to order the 7075 receiver extension, but am afraid of receiving the 6061 extension. How can I spot the difference between the two, or are they identical in appearance?
Thought about asking the same thing myself. The same picture is used for both the 7075 and 6061. And then there is the listing for the DSA tube. And then there is the tube as pictured with the stock kit.
