Not very functional - Firefield 5x Tactical Magnifier for Weapon Sights

This optic is very clear but not functional as far as holding zero. It comes with a fixed Mount not a flip mount and there is no windage or elevation turrets. The optic is very bulky near the viewing lens. The problem with this is if you buy a flip mount it is nearly impossible to have backup sights underneath of it as well as get to your charging handle when flipped to the side. If you wanted a magnifier just for scouting or viewing long distances then this would work well as far as looking through a holographic or Dot site I would not recommend it.
