Best offset irons available - Magpul Industries MBUS Pro Offset Deployable Iron Sight

The functionality is superb, personally I prefer offset BUIS than those in line with optics, trying to use BUIS through red dots are cluttered and clumsy, if you truly meed to use BUIS, wouldn’t you want them to be as useable as possible? I try to put them on every upper, they just take some practice to get used to (just like everything else). They are low profile and stout, if you break these you are probably trying to do it on purpose or have no concept of the torq needed to secure them.
