Glass is great. Especially for a 42mm objective. I compared to my 5-20 50mm Razor HD and the glass is just as good. Slightly better than my 3-15x44 pst gen ii scope. The PST has a slightly larger FOV but it's foot print is much larger and heavier. This is my only SFP score and lives on a christen arms 223 bolt gun. A very light package with this scope for a 20" barreled gun.
