Great product but there is a "but" - Unity Tactical Top Mounted Deployable Iron Sight

I love the FDE color on this, the product is great. Cratsmenship and quality is superb. However the only downside is you have to use their hub. I bought the hub thinking i'd like it but the added wing on the hub to mount a weapon light or whatever else in their UT ecosystem just looks out of place if not used. So if you want to mount a weapon light compact then use this system.
