[TINMAN]

I recently purchased an Eotech 516 and mounted it on my S&W MP 15. I took it to the range yesterday. I sited it in at 25 yrds. and proceeded to put 6 shots dead center. I then went to 50 yrds and put the dot on the bull. I fired 4 shots and all were about 4-6
inches high. I did not have the manual with me at the time so I am asking if there is some sort of lock on the adjustment? Could it have moved that much or could I have moved that much. Any advice would be appreciated.

It makes perfect sense. At 25 yds, the bullet is still rising.

i was just going to post that, at 25 yards you are about 2 1/2 inches high

Would a compensator affect those trajectories much or is it inconsequential?

It would have little to no effect. It all has to do with the offset between the barrel bore and the scope or sights.
