Help with a new gadget I want to make

i just got the Crown and have installed a rail on the stock so I can mount a bipod. Being the way the Crown has been designed the bipod if roughly in the center of the rifle. I want to do something to mount the bipod forward by 1 foot. I have a piece of 1inch square aluminum tubing 1/8” thick on one end I will mount a rail that a bipod will attach to what do I put on the other end to connect to the rail on the rifle. Other than taking a bipod apart to repurpose the rail clamp I don’t know does anyone sell a rail clamp that can be attach to my aluminum tube. The reason I want to do this is I have found that the longer distance between the bipod and my shoulder the better I shoot. The added length keeps my point of aim more steady 
 
I just ordered a length of 1.125 dia .125thick aluminum tubing. As per Perculas suggestion on one end I will attach either 1 or maybe 2 scope rings that I had laying around then I can clamp it on my Crowns bipod rail. On the other end I will attach a Picatinny rail for my bipod . I’ll then give it a few coats of spray can flat black.I will report back to all interested on how this setup should improve the accuracy of my shooting, the best way to describe it is when the balance point of the bipod is put slightly forward of the end of the barrel it seem to give you a fine tuning on your aim point resulting in better shooting results. The downside is makes the rifle a bit more clunky to handle but since I’ll be on a bench it won’t matter.
