Buyer beware - Troy Offset Deployable Iron Sight, AR-15/M4

Ordered these earlier this year to fit into a custom carbine. After finally receiving the carbine, I went to install these iron sights and ran into two major issues. First issue is that I couldn’t even get the front sight onto the rail. I’ve searched up and down the internet to see if anyone else had this issue, to my surprise I’ve seen one person with the same problem. However, I was barely able to get the rear sight on and had to use wax so it wouldn’t severely scratch the rails all up. Once I got the rear sight in place, I noticed that when I fold it down, it’s a millimeter from my radian raptor charging handle. Even if this was an oem CH, you’d still have issues grasping the CH. Id also note that this is as forward as you can get the mount due to the brass block impeding the mount. At this point I’m still trying to contact Troy to see if there’s a way to work this issue out. One star because they’re unusable and because opticsplanet will not allow an in-house warranty claim, as I’ve exceeded their return policy timeframe, even though I just opened the package. If I’m able to square this with either company or find a reasonable fix for the sights, I’ll update this review.
