I went with the accu-strut. They are all based on the same principle so I didn't see the point of paying more for the mo-rod.
This is exactly right, they'll both have the same impact on accuracy. I actually built my own from a few UTG barrel clamps and a piece of aluminum rod, all of which cost me less that $30 and worked just as well to improve the accuracy. So depends on what you're willing to spend really since any of the barrel struts will give you the same benefit.
