I like the Stoney Point Rapid Bypod. Have one on my remington 700xcr 270wsm. Steady and rotates 360 degrees also gives flexabity if you need to canter the gun on uneven ground. Connnects to gun quickly and I use it for a walking stick.Took a doe last season at 298yds. knealing. Also hitting rocks out to 500yds. in the sitting position. Heres a link so you can look at them.
