With most red dots the glass isn't of the best clarity and I'd rather see most of the target area without a blue-tint
my only complaint with scout type rails is heat. A lot of heat transfers to them and gloves are a huge asset after just a couple magazines.

As long as the amount of heat imparted to the "scout" type rail does NOT affect the electronics inside the rail-mounted optic, the rail absorbing a certain amount of heat and reducing barrel heat-up may be a positive feature.
It may be that users who switch to a smaller I.D. gas bushing in their Mini-14s may obtain some slight benefit as regards the amount of hot gasses (heat) injected into the gas block. It has been noted that reducing the I.D. of the gas bushing causes the projectile to exit the barrel at slightly greater velocity. The hot gasses thus forced out the end of the barrel are thus not available to heat up the gas block, rail, and so forth.
Some users have drilled small diameter holes down the centerline of the stock's fore end. The theory is that these holes allow relatively cold air to enter the bottom of the fore-end, circulate around the inner metal heat shield, exit the top of the fore-end, and so provide a little additional barrel cooling.
I don't know of anyone who has done a before/after test concerning these features/mods, so (except for increased bullet velocity) the precise effects of these mods is guesswork for now.
