Not sure if they still make them but I got a Vers-a-pod many years ago and I really like it. The base installs on you front sling stud and you can still attach your sling. the bipod itself can be removed and carried in your pack until you need it. And you can get two lengths, one for lying and and another for sitting-kneeling and they are interchangeable. Plus you can buy additional bases for your other rifles.
