A TacticalGear.com purchase. Looking forward to getting a few more, especially the Prizm shooter kits. I now know the difference between the standard Strike and Agro lenses. I also know that 2.0 and 3.0 lenses are in fact compatible even though the retail images might look like they would be different. If I had known my 2.0 came with Agro lenses, I could have picked up an Agro 3.0 instead of this one. Oh well, still a keeper.
