Mounting bipod

[Rust]

From the last picture it looks like the tension screw is at a considerable angle relative to the legs and the body of the bipod. Makes me think the tube is offset, or something is out of whack in the bipod base. A way to check if things are mounted parallel to one another is called "boning". Where you use to pieces of metal or dowel to check parallelism. Couple ways I usually go about it. Either pull your scope, and set the receiver upside down on a flat level surface. (you'll need to weight or strap it down or block the barrel up to keep it from leaning forward.) Put a tight fitting dowel or drill bit into the hole of the sling stud and take a step back to compare if the dowel or whatever is at the same angle as the table the receiver is sitting on. Works best if you have a long drill bit or piece of drill rod that will fit the hole perfectly since a smaller piece will want to lean to one side. Or can also do this in an action vise or something similar to avoid pulling the scope. You just need to have a set up that will keep everything solid and level enough to balance one "bone" on the top rails so you can hold the other square in the sling stud hole unless you have something that will fit it without sagging to one side.
