Vector optics come in two different bolt patterns, one is the same as the Trijicon red dot (RMR) and one is the same as Docter/Shield/Sig Sauer/Vortex.
If you have the one that so the same as the Trijicon. you’ll need to find a specific adapter.
If the bolt holes line up you’ll need to make a spacer plate so that it doesn’t sit on the TM sight posts.
Got a link to the sight you bought?
I just checked, yours has the Trijicon spacing
