Detailed Reviews

Arken Optics EP5 5-25X56 Rifle Scope FFP

Arken EP5

This is hands-down one of the most impressive scopes I’ve tested under $400. I mounted it on a .308 bolt-action using a 20 MOA base and zeroed at 100 yards in about 12 rounds.

True FFP reticle
Cons
Heavy

Glass clarity is excellent for this price range. I noticed minimal chromatic aberration, and the image remains sharp even at 25x.
Eye relief is around 3.5 inches, and the eye box is forgiving at mid magnification but tightens at higher zoom.

Turrets are tactile and precise. My box test confirmed accurate tracking.
Magnification and parallax adjustment make it ideal for long-range target shooting.
Mounting requires sturdy rings due to weight.
