I have a LW Midlength Flattop Rock River Upper and recently put an Elzetta light mount on it.  I love the light mount but the flashlight and mount is not centered with the barrel.  Elzetta even sent me a second mount to see if that was the problem, but it wasn't.  The A2 FSB seems to be off to one side (while looking down from the top with barrel pointed forward the light and mount is more towards the right) is this common or am I just being too picky?  And if so will Rock River or any AR upper producing company fix this or is not a concern of theirs?

if it is canted, we can fix it (assuming factory installed FSH to begin with).
Please call 866-980-7625 and ask for Technical.

I sold my first upper to my dad and then bought the same style of RRA upper from RB Precision.  I put my Elzetta light mount and the same thing happened, but to a little less degree.  The light is not perfectly centered under the barrel, it is off to one side.  I have had three RRA uppers and they look and function great, but what is the problem on having the A2 front sight 100% true on installation.  Is this a difficult process?  Or am I just being picky expecting perfection?
