B Square lasted about 5 rounds before the bubble fell out on the ground ... I layed the superglue to it and it's stayed in place since. Mine is on a picatanny rail positioned just forward of the "scopes" eye piece. I normally get on target then glance down and to the left to check the bubble. If everything is good then I proceed. Can't see how you could possibly sight on target and referance the bubble level at the same time.. So regardless of position on said firearm as long as its visible from behind the scope "per referance" you should be golden!!!
