I have a similar setup for mine (cheaper version of holosun QD red dot). I don't have the angled foregrip, instead I have an adjustable foregrip can go from flat 0, to 30, 60 and finally 90 degrees (vertical).
That grip is pushed up further so I can remove my scope and attach it to the bottom rail closer to the trigger guard for safe transport. I will try to put a picture up later today.
