I put a pica tinny rail on my TX22 Competition SCR so I could mount my Red Dot sight. Picatinny rail installs just fine (only two screws). Problem is getting the Red Dot to sit squarely after mounting it on the pica tinny rail. Regardless of what I try it always seem to sit "cockeyed". This is the ADE RD3-015-PRO Red Dot. Could it be the rail not letting the red dot not mount flat. See pictures. Thanks in advance for any help/suggestions.
My ADE sights I mounted directly to the factory base. I removed the rail mount like you do for a battery change and found the correct screws at an ACE hardware. It works well, and lowers the sight. Mine are the RD3-006 Green dots.
