Works as it should, very impressed. Simple addition to a standard style rifle to make mounting to a tripod a breeze.
Finally, a bipod that works for all positions. Used with shorter set of legs on several rifles via pic-rail mount off the bench. Changed to longer set of legs for prairie dogs today, and performed flawlessly. A few quick adjustments allowed me to convert from shooting prone, to sitting, to prone, etc.
Used Pic-rail adapter (included) to convert sling stud on my Ruger Hawkeye to a pic-rail for use with this bipod. If I had one improvement, I'd suggest adding a thin pad to the surface of the adapter where it meets with the rifle forearm.
Haven't used on any big bore rifles, but certainly a winner on my 223REM and 204RUGER. I consistently killed prairie dogs out to 300 yds. Wouldn't be able to do that without the solid support provided by this bipod.
