The scope was attached so poorly that it could not be aligned. Only after the Ballistics Laboratory of the U.S. Army repaired the improper mounting could it be semi-accurately fired.

What is hard to understand about that? Now you are reduced to defending the work of Klein's gunsmith? And you want to argue with the FBI about this?

Robert A. Frazier, FBI expert testified to the Commission about this "When we attempted to sight in this rifle at Quantico, we found that the elevation adjustment in the telescopic sight was not sufficient to bring the point of impact to the aiming point. In attempting to adjust and sight-in the rifle, every time we changed the adjusting screws to move the crosshairs in the telescopic sight in one direction- it also affected the movement of the impact or the point of impact in the other direction. That is, if we moved the crosshairs in the telescope to the left it would also affect the elevation setting of the telescope. And when we had sighted-in the rifle approxiamately, we fired serveral shots and found that the shots were not all landing in the same place, but were gradually moving away from the point of impact.

This was APPARENTLY DUE TO THE CONSTRUCTION OF THE TELESCOPE, which apparently did not stablize itself-- that is, the spring mounting in the crosshair ring did not stabilize until we had fired five or six shots....There is an elevation-adjusting screw at the top, which pushes the crosshair ring down against a spring located in the lower left-hand side of the scope tube circle which adjusts the crosshair ring laterally for windage adjustments....We found in this telescopic sight on this rifle that this ring was shifting in the telescope tube so that the gun COULD NOT BE SIGHTED-IN merely by changing the screws....to the point that we decided it would not be feasible to completely sight the weapon inasfar as windage goes, and in addition found that the elevation screw could not be adjusted sufficiently to bring the point of impact on the targets down to the sighting point....As far as to be unable to adjust the scope, actually, I could not say when it had been introduced. I don't know what the cause is. It may be that the mount has been bent or the crosshair ring shifted...."

MR. EISENBERG: "Carrying this question a little bit further on the deliberateness of the sighting-in, the problem with the elevation crosshair is BUILT INTO THE MOUNTING OF THE SCOPE, is that correct."
FRAZIER: Yes. The mount is not screwed to the rifle in such a fashion that it points the scope at the target closely enough to permit adjusting the crosshair to accurately sight-in the rifle....You can accomplish that merely by PUTTING SHIMS UNDER THE FRONT OF THE SCOPE AND OVER THE BACK OF THE SCOPE to tip the scope in the mount itself, to bring it into alinement."

In other testimony gun shop owner Floyd Guy Davis was asked "If a man purchased a from a mail-order house that had a telescopic sight mounted on it, would you have any opinion as to what the accuracy of that rifle would be without it having actually been sighted in by actual firing of the rifle?"
DAVIS: "If the gun was anywhere near accurate, IT WOULD HAVE TO BE AN ACCIDENT, because the slightest jar CAN KNOCK A SCOPE 2 OR 3 FEET OUT OF BALANCE, and there is no way you could ship a gun AND CARRY A GUN AROUND A LITTLE BIT and make sure it being accurate. That is why your deer hunters practice and shoot their guns in every year before they go deer hunting. And I have saw them waste almost five boxes of shells trying to get them accurate down there after having sighted them in the year before."
