The RAM Optics 4x40 AO offers a decent quality and good features for a low price.
Adjustable objective (AO)
The objective lens can be focused on target to get a clear image and reduced parallax effect.
The ocular lens (rear lens) can be adjusted to your eyes to get a sharp image of the reticle.
This feature is a must for people with reduced eye-sight (wearing glasses/lenses).
Thanks to the nitrogen filled tube there is no oxygen inside this scope, preventing fog inside the lenses.
