The pin holes in the rear sight block are often located inconsistently as a result of the original manufacturing process. The two holes are frequently not parallel to each other and may be out of alignment or skewed. The mount can only accomodate so much of this misalignment. You should measure the center distances from pin to pin on both sides and check those with the dimensions listed in the SPECIFICATIONS to ensure that the mount will fit properly. A 3mm drill is provided and can be used to clean out and straighten (to some degree) without enlarging the pins holes once the pins are removed. The pin holes for the rear sight block are generally .118″(3.0mm) in diameter and the supplied 3mm bolts have a nominal OD of .115″(2.92mm). This tight fit along with the use of an appropriate liquid thread locker for the screws and nuts, as well as proper tightening of the same should result in no movement of the Mount during normal firing recoil. Occasionally the rear sight block itself, as it sits on the barrel dovetail underneath, can be out of alignment with the bore axis. This condition, if extreme, can adversely effect how the Mount sits.
TOOLS REQUIRED: Safety glasses, heavy gloves, solid work surface or vise, hammer, flat blade screw driver, 7/32” (5.5mm) socket driver or wrench, hand drill, and liquid thread locker. A MAPP (Methyl Acetylene Propadience Propane) gas torch and heavy duty punch may be required to remove existing pins from the rear sight block if they are soldered in place. You can usually find these items at your local hardware or plumbers supply. The application of heat, if done properly, will not cause damage. Keep in mind that you only need to reach the melting point of the solder and that this same temperature was achieved during original construction without adverse effects. Procedure provided in supplied instructions.
NOTE: As with ANY scope on ANY mount, should it receive an impact (dropped, hit, etc.) it should not be trusted to be accurate. Thus the SEE-THRU feature of our Mount. You can always still use the original iron or open sights if you feel the Mount has been compromised. Design subject to change without prior notice.
Caution! Improper installation or use may result in damage to property, severe injury, or loss of life. If for any reason this product does not function properly, discontinue use immediately. Always practice proper SAFETY & ensure an UNLOADED condition before beginning installation.
