Could Primary Arms (PA), or some of the blog followers, put up a thread sticky that lists each of the PA sight dimensions and how the different sights fit on popular weapons.
I'm new to PA and their products. It took a bit to figure out what red dot and magnifier combo to mount over my Magpul rear backup site in the standard AR flat top length. Then figure out an AK system.
It seems that other people are asking similar questions and it would be cool to have one place to look on compatibility of mounts with pictures.
I have to say - great pricing, exceptional service, and outstanding shipping times had definitely made me a Primary Arms fan.
