Cycles smooth - POF USA AR-15 Roller Cam Pin Assembly

I can feel a slight difference charging the rifle but I imagine something rolling vs a rectangle piece of steel dragging along is probably better for wear. I will add a negative, it makes indexing the bolt cam pin into the bolt so the firing pin can drop through, more difficult. With the little roller bearing spinning you have to eyeball it and stab it a couple times and visually look through the BCG to make sure it’s lined up. In a low light situation this could be a huge negative. With a rectangular cam pin its fast and easy to spin into place. I can see the advantages and that might be fine for a non-duty weapon and I will probably run it on one of my ARs but for the reasons above I wouldn’t recommend it.
