Hey. Question, and not sure if I am doing this correct. Recently bought an MK IV standard 22/45. Installed the TK Fiber Optic sight cause the original that came with the gun was all black and tough to see.

My issue is that I noticed the factory issued issues I taller than the TK one. Now, with the picatinny rail, I can only see half of the TandemKross Sight. I’ve tried raising the rear sight but it gets to the point where I have to raise it until it comes loose.

Am I doing the install right, does anybody else have this issue. Debating if I should just reinstall the factory version.
