So I have an mlok rail on one of my rifles. I have a Nikon P-223 scope on the picatinny rail on top of the receiver which leaves no room for a rear flip up buis. I was hoping to put 45 degree canted sights on the right side by mounting them to the rearmost and frontmost mlok slots on the top of the rail. However, I can not seem to find any 45 degree buis that will come with mlok slots. Am I SOL? Do I really need to buy 45 degree mlok to picatinny adapters just to put buis on them?
