Before you buy one. You should try out a Versa-Pod. I've used a Model #1 for quite afew yrs. Has adjustable locking legs, pitch & yaw. Et snaps on-off, in a few seconds. Also once you mount the [bipod mount] on your rifle. You can buy different lengths of "legs" for prone or sitting. That fit onto the same mount.
95% of my shooting is prone. The rest is on the fly /ubbthreads/images/graemlins/grin.gif
