I just looked at the specification for the PA 5x prism, FOV is 18.8 and 2.5-3 eye relief. The field of view on the prism 5x is pretty much the same as a Vortex PST II 1-6 on 6x. The eye relief and eye box is kind of restrictive on prism scopes especially if your used to using a red dot sight in a similar situation. Elcan deals with this issue with a 1x or 4x selectable prism which is more user friendly but are very expensive. The US military used ACOGs which were usually max magnification of 4x. The FOV on a 3x is prism over 39 compared to the 5x 18.8 so basically boils down to intended use.
