Compatibility: Only compatible with Malcolm 6X Gen II Long Scope. Included: The reticle is pre-installed within the brass housing tube. (Note: The Malcolm 6X Gen II Long Scope ships from the factory with the 0.001" fine crosswire already installed.) Reticle Replacement Procedure: To swap your reticle, follow these steps carefully: Step 1: Disassemble. Remove the eyepiece and loosen the two set screws located on the reticle lock ring. Step 2: Remove the Reticle Tube. Elevate the objective end of the scope to a maximum angle of 20 degrees. Carefully tap the objective end with a dead blow hammer, and be prepared to catch the brass reticle housing as it slides out of the eyepiece end. Step 3: Handle with Care. Warning: Do not touch the exposed reticle wire. The wire is extremely fragile and will easily deform or break upon contact. Handle the assembly by the brass tube only.
