I had a 1-8 Strike Eagle (sold it recently) and the glass was much better than the PA. Maybe PA gets the rebranded QA/QC rejects.
I was shooting a dual-fuel (fiber and tritium) Green Cross ACOG today, and had to cover the fiber in the sun to keep it from blooming too much. This is only an issue with the cross reticles. I've never had it happen on the chevron, horseshoe, or dot.
