I have owned a Harris 6-9 as well as a 9-13 for many years. Always seemed to have the wrong one on when I needed it. For the last 2 years I have been using the Stoney Point swivel bipod (short prone model). The legs are flexible and can be spread apart to get lower or brought together to raise your rifle. Are they as sturdy as a Harris - NO - but they sure work just fine - particularly if you use a rear bag. And they pull off and go back on in less than a second on your rifle. Not only that I can finally use a bipod when I'm a horse back and need to scabbard the rifle without untightening a bolt that attaches to your swivel. Nothing beats a Harris if it fits your needs.
