If you just want stability and are not interested in moving the mount forward in front of the stock like Dave Hobeck shows, I recommend a Sinclair F-Class Gen-3 bipod.

I use one with my 12 LRP with a 26-inch barrel and it is as stable as anything I have ever used.
It mounts on the front sling swivel and tightens down. No need to front load the F-Class bipod.
I fact I use one with all of my target rifles from a bench.
Actually, I believe it was made for use prone but after using it from a bench, I was sold.

About 8 of my range buddies who saw my results and got to try one of my two bipods on their rifle were sold too. They all now have purchased their own.
