A scope mounted to the carry handle will likely be far too high to be effective, unless you get a serious cheek pad. A lot of guys do it, but they typically have red dots or reflex sights because eye relief and exit pupil aren't an issue - the bullet is going to go where that dot is regardless of where their eye is.

If you do get the one with the handle, mount a scope, and don't have a good cheek weld, you'll be stuck using a red dot because you won't be able to utilize a magnifying scope correctly. The offset between where the scope should be to line up with your eye is just too far off.

If you want a scope AND a red dot or reflex, Warne makes the RAMP system for the AR so you can do both:
Warne RAMP30 (30mm scopes)
Warne RAMP1 (1 inch scopes)

I personally don't see the added value in the carry handle. Get a flat top AR (they are designed for magnified optics), put a scope on it, and if you decide you want a carry handle, get a used one on Gunbroker for $75 and you can swap them out. You save $160 bucks and get both.
