I have this behind compm3 LT cant. mt Iwould like to know if anyone has had a problem with damaging the magnifer from ejected shells when fliped to shell deflecter side, I turned my mt around so it flips to the left,was this a good idea or should I have just left it alone, all feedback greatly appreciated thanks .
I had the same set up and had no problems.
If you are right handed you want to the pivot mount to rotate toward the ejection port side of the gun so the magnifier is out of your line of sight when the magnifier is pivoted to the side.

yea but what about shell deflection can it damage the magnifer when its fliped to the right thats my real question
As I stated in my first reply “No problems”.
Spent casings do not hit the magnifier when the magnifier is pivoted to the side (on the ejection port side of the gun).
Ditto. I have mine on a Samson flip mount (for now) and have never seen a spent casing come close to hitting the magnifier. The casing would have to eject up and back AND clear the built-in deflector for that to happen. FWIW.
