I ordered an FWB 18mm front globe sight for my Mrod aperture sight project. It's a hodgepodge of decent parts so far at the rear (Gehmann adjustable iris on a Williams TK base). Looking to improve the front sight a little bit and this one will accept Gehmann front irises. So this opens a new rabbit hole, provided I can design a mount that keeps it low enough to use at short ranges (thinking 8 yards and out). The current front sight is a simple 3D printed blade on top of a cup that slips over the shroud and moderator adapter (and held in place by the thread protector or a moderator). It works pretty well, but I'd like to modify it to a dovetail I can install this globe sight on. If it works out, I can see myself diving into front irises . If not, I'll probably sell it.
You'd think this stuff might be cheaper than a scope, and it is if you aren't stupid like me. With this purchase, my Mrod aperture sight system is pushing $225 or so. But it is far lighter than any scope you can put on it at that price point and 10x more fun.
