These are gaining popularity so I thought I'd throw up some pictures. I used the sight in the iron man 3-gun match and it stood up very well. I like it as well as the J-Point and the Doc Opt plus it has a few options not available on the other two, namely the on/off switch and the top access battery door. Also the sight has a replaceable aluminum hood. The down side is that it is slightly larger.
The ACOG mount I have is a PF and I think it is too large. It offers a lot of protection but is bulky and could stand to be redesigned.
These pictures are a little dated so if anyone wants anything specific just ask.
