I recently got a few iron sighting systems from Ameriglo.
Front: GL-212-OEM-200-125: Proglo OEM
Rear: GL-80070 Serrated U Notch
This set is known as the "Spartan Operator Sight"
These sights are very much like the Ameriglo Pro-I Dot Operator sights which I reviewed, along with two other sets. Stay tuned I'll be posting more photos of the other sighting systems I received.
