OK Im having a custom rifle built that will be done in the next two weeks. I have an atlas bipod that connects to regular rails. I picked up a spigot on ebay.. but I figured out I need a different atlas bipod... Or is there some attachment I can buy for my spigot in order to make my bipod work... boy am I glad I bought my bipod when they were cheaper.. anyways thanks for any help you give me here..
