I know this is a little out there, but this is what I'm using on my main target rifle and there great. The width of the legs is grand compared to my others. Like 0933 said theres all kinds of knock offs. Some are good -- some are ok and most are junk. As with anything in this world -- you get what you pay for.
I use my bipod a while Long Range hunting so I want a lightweight bipod. I use the Caldwell pivoting bipods. Made very similar to a Harris at half the price and I've had zero issues with the 4 that I have. I have one of nearly every size for different applications and locations that I hunt.
