Arken Optics EP5 5-25X56 Rifle Scope FFP
This scope is one of the best budget-friendly long-range optics I’ve used. It punches far above its price class and is ideal for serious target shooters.
Product Specs:
- Magnification: 5-25x
- Objective Lens: 56mm
- Tube: 34mm
- Reticle: FFP VPR MIL
- Turrets: 0.1 MIL
Pros:
- Excellent tracking accuracy
- Large objective for bright image
- Solid turret feel
Cons:
- Heavy
- Requires quality mount
Glass clarity is surprisingly sharp with minimal chromatic aberration. Edge-to-edge clarity remains consistent even at 25x, which is rare in this price range. The FFP reticle is precise and extremely useful for holdovers.
Eye relief feels comfortable around 3.5 inches, and the eye box is forgiving at mid magnification but tightens at max zoom. That’s expected for a high-power optic.
Durability is excellent. I mounted it on a PTR-style .308 platform using a 20 MOA mount, and it held zero after 400+ rounds. No shift observed.
Turrets are tactile and audible. I performed a box test, and tracking was reliable with no noticeable deviation.
Magnification range is ideal for 100–800m shooting. Parallax adjustment is smooth and accurate.
Mounting requires a solid 34mm mount due to its size. Accessories included are decent.
From my experience, zeroing took about 12 rounds. Once dialed, it stayed consistent even under recoil.
Online forums praise its tracking reliability, though many note the weight.
Verdict: Best budget long-range option.

How to Choose the Right Scope for This Pistol
Choosing the right optic for a PTR 91 requires understanding both the rifle’s characteristics and your shooting goals. The PTR 91 is a .308 platform with strong recoil and excellent accuracy potential, so your scope must be durable and capable of precise adjustments.
First, consider magnification. For target shooting, I recommend at least 4-16x. If you’re pushing beyond 500 meters, a 5-25x scope gives you better precision. However, higher magnification often means tighter eye boxes and more weight.
Second, focus on reticle type. First focal plane (FFP) scopes are better for long-range shooting because the reticle scales with magnification. This allows accurate holdovers at any zoom level. If you’re just shooting at fixed distances, an SFP scope is simpler and cheaper.
Third, turret quality matters. The PTR 91 benefits from accurate dialing. Look for scopes with tactile, repeatable clicks (0.1 MIL or 1/4 MOA). Perform a box test if possible.
Durability is critical due to recoil. Choose scopes with solid construction and good warranties.
Finally, mounting matters. A 20 MOA mount helps extend your elevation range for long-distance shooting.
