That was one of the issues that came to mind when I first saw the product. The bipod being out that far creates a longer lever acting against the screws."shortslide"
Wondering if the long version could wreck the four screws holding it onto the frame if enough force was exerted on the top of the gun above the bottle, like he did in the video? Put another way, would the rail bend before there was enough pressure to damage the four frame attachment screws, whereby the frame attachment screws would de-thred?
