I just mounted my Larue tactical eotech mount on my flattop bushy.  I mounted it where the mount would fully sit on the flattop.  So the problem is with the buis, I have a YHM flip up buis and can only get 1 screw into the thing because both holes wont line up right if i have the larue mount on the flattop fully.  Woul dit be OK to just have one screw in it or is there anything I can do??  The buis feels tight with no wobble with one screw, just looks kind of funny with an empty hole..  Any help would be appreciated.. I know i probably shjold have got the buis eotech mount combo, but i didnt think of that when i ordered all this.  Thanks!!

What YHM BUIS are you running?  Mine is the A2 Flip Up and it ONLY has one screw...  You sure you don't have their standard fixed rear sight?

B.M.A.S clamp on rear sight (YHM-9440)  i guess I need to change it for the B.M.A.S low profile rear flip sight (YHM-9680)

Exactly
