Good info about the rear one - didn’t know it was there. I’ve never used that one (always used a Harris or Atlas).
Iego, FWIW, a bubble level isn’t a bad thing to have when properly used. A bipod which has multiple axis rotation is great for getting off the bench (uneven ground, propping on obstacles, etc.).
If you are invested in a nice rifle and monopod already, consider an Atlas bipod. Look for a used one if you want to save a little money.
