Can a trijicon reflex with cantilever mount be fitted.............on a A2 carry handle with a 7 inch barrel with a standard FSB?

I am already purchasing parts and started receiving them also, but I didnt want to buy the cantilever
mount and it not fit. basically I am building a small A2 upper but I would like to fit a Trijicon reflex sight on it by using the cantilever mount.

I think it might fit but it might look too long.

heres some pics to show you what I am talking about..................
