Nope, it attaches to the sling swivel directly. Thats the one I have as well, great bipod.
One thing, if it comes loose every now and then after a few shoots (completely normal) then use some blue loctite on the screw and that should fix it.
Oh, hold on a minute.
Your talking about actually rotating the gun left to right.
You are going to need a rail to accomplish that. Harris has an attachment that connects to the rail, and you hook the bipod onto that.
The "S" models let the gun cant left and right, but not turn. Does that make sense?
Look here on the Harris homepage for that attachment. You should be able to find it somewhere to buy it.
I have a savage edge (now axis) in .308 and one in .223. They are not good bipod shooters due to this flex. It takes more willpower than i have to not pivot and flex the stock on the next shot at a different target. On a bag or soft rest the problem doesn't exist. Perhaps a monopod where the swivel stud is would work too. As a reference, my .308 shoots consistently around 2 inch groups + or - 1/2" at 200 yards with my handloads. With a bipood they are 4 inches and up and not very consistent at all.Harris 6-9 inch have used on every thing from 22lr though .375 H&H mag.. Attach to sling swivel and then attach sling. One must watch synthetic stocks often flex and can change point of aim.
