Buyer beware! - LWRCI Skirmish Back Up Iron Sights Set

I REALLY looked forward to getting these sights, and I was happy to receive them exactly one week ago. These are the coolest looking sights, but problems lurk beneath. (1) I could not fit the front sight onto my AR-15's Seekins' rail. Well, it fit onto my AR-10's rail, so no big. I could swap sights. (2) the detent for the front post is offset 45 degrees from where every other manufacturer (like Troy) puts their post detent. This means You can only use an after market post made specifically for LWRC, and I could not find one. Huge disappointment for me. (3) The windage adjustment on the rear sight spun almost freely. No kidding. It could easily be moved with my pinky, making it too easy to lose my zero-point-of-aim.
I must be mental, because I was still willing to keep the sights. I decided I could paint the front post with glow paint or something. But when I called LWRC and spoke to the rep about highlighting the front post, he told me that people don't worry about such things because it's just a back-up iron sight, a BUIS. I thought, "wow, $200 for a sight that does not really matter?"
Thankfully I purchased the LWRC Skirmish sights at OpticsPlanet.com and two hours later the sights were on their way via FedEx for an exchange to Troy's Battle sights.
