Personally i don't like the idea of anything hanging off the barrel & changing harmonics, and pressure on the barrel, especially if I'm shooting at ranges long enough to want a bipod I'd go with something on the forward sling swivel. I have been dabbling in the long range (Ernie might argue what defines "long range" and I will respect that!)rifle stuff for about a year, on a range that goes out to 1000 yds. It's amazing how much the point of impact varies when you hand something on the barrel or put pressure on it. For field stuff with the rifle I usually use my backpack.
