On EBAY, I just recently won the bid on a new one for an AR build I am currently working on. It's the real deal, not one of those Chinese air soft knock offs.
Anyway, I was looking it over and am very satisfied at how well it's built for a poly sight. One Q? though; Why is the adjustment knob so hard to turn/click? Is this normal with this sight? I am guessing once I get it mounted and start adjusting it, it will loosen up. I removed one of my current AR sights and installed the MAGPUL to check it out.

I find mine real easy to turn clockwise or windage to the right, but I find it much harder to turn counter-clockwise or windage left. No idea why.

Yes, this is what I meant to state. Mine is the same way. I thought it might have been just mine. Anyone else out there have one that is like this? If it's normal, then, I guess I will have to get used to it.
