Sounds to me that you have an AR15 front sight on your AR10.
An AR10 has a bigger and taller receiver than an AR15 and thus requires a taller front sight.
I went to Bravo Companies web site and I did not see any AR10 accessories there, just AR15's.
The top sight is for an AR10 gas block and the bottom sight
on the left is for an AR15 gas block.
