Dytac Aimpoint Micro T-1 mount issue

[Diffusion]

I recently bought a Dytac micro T-1 with the SOCOM QD mount, and when I went to mount it on my gun, I found that the mount was perfect size for the rail. However even with the QD released the mount wouldnt fit onto the rail because the mount opening was too small.
i was wondering if this was a design flaw or if it was made for a different type of rail. and how i could possibly fix the problem

thanks for all your help =]
