Help with BiPod choice

Just put a new scope on. Looking for a bipod that will attach to a rail. The Harris bipods that I have seen all attach to the lug. I don’t want to buy a adapter too. Not sure how long the legs should be. Rifle will be used mostly at the range. Should I get one that swivels? Here is a pic of the gun it will be going on.

There are a few threads here if you use search that discuss bipod options. Here’s a thread on bipods with a poll.

As I recall, some leading bipod options are:

You can find advocates for all of these. For me, the Harris + mount works for range shooting and combined cost was still less than the others.

Harris is a good Bi-pod with a good price.

A buddy used a Harris on his M249 while in the Army…He stressed how robust it was.

So I got one and it has held up to my “abuse”…one example:

My rifle fell off the back of my ATV, and down several feet hitting rocks on the way, while cruising along a creek bed…was still locked on tight and nothing was bent. Except my front sight post…

Edit: The one I got had a rail attachment come with it. I can attach it to the rail on me foregrip (MOE).
