Black specs falls on lens. - Athlon Optics Argos BTR 8-34x56mm Side Focus Rifle Scope

As time goes on, eventually black specs from the internal oily coating starts falling on the lens. The lens are as clear as vortex but the quality control of manufacturing is not. I saw lots of oily debris and even lints looking through the objective lens. Save the money and buy a better brand that will last a lifetime not spend a lifetime sending it back for repairs.
