For those of you running these rails, do you have any issue with heat transfer to your optic? Debating on a T1 or a RMR on the top rail but am worried about heat transfer to the optic frying it.
Both the UM and MI get pretty damn hot if you are running an AK hard in my experience. I have gotten a T1 riding on a UM hot enough that you couldn't touch it and the optic was still functioning perfectly. I have come close to doing the same on a MI equipped SGL. For that reason I am confident recommending a T1 but VERY cautious doing that on the RMR.
