So is the receiver drilled incorrectly or the extension tube drilled crooked? I looked at the picture and cannot figure which is faulty. As others posted, each tube can be inserted into the receiver individually and pinned, then the clamps are applied. Once fully assembled and tightened, there is no reason to touch the clamps and the double truss can be installed or removed as a complete assembly.
The extension is drilled incorrectly.
We tested the insertion/removal once all install steps were followed. The entire assembly would not come out. We believe it is the thick powder coating that was applied to all parts. It makes for a tight fit. Plus, the tolerances are quite tight to begin with.
After a few ins/outs, it should be fine.
