Air Marksman Backbone Rail

What everyone have said but it is especially noticeable with 700mm shooting at high power. Not as noticeable when shooting with 500mm at low power like 20fpe. If you shoot pellets at low power with 500-600mm barrel then it’s really not all that noticeable.
Thanks......that's what I'm shooting is the 700 mm .25 cal......Looks like I'll be ordering one very soon....Thanks...:)

Nearly every one of the Impact's competing in the RMAC this week seem to be outfitted with one, so I'd bet it's a good investment in accuracy. I bought the shortest version a few months back, as I don't need extra weight out front. I like how it stiffens up the chassis and components compared to the original top bar and separate picatinny rail.
