Detailed Reviews

Arken Optics EP5 5-25X56 Rifle Scope FFP

Arken EP5

This scope is my go-to recommendation when someone wants maximum performance without spending over $1,000. On the M110 platform, it feels purpose-built for long-range target work.
Product Specs
Magnification: 5-25x
Objective Lens: 56mm
Tube: 34mm
Reticle: FFP VPR MIL/MOA
Eye Relief: 3.6 inches
Pros
Excellent turret tracking
High-quality glass for price
True zero stop
Cons
Heavy
Stiff magnification ring
The glass clarity is impressive, especially for a budget optic. I noticed minimal chromatic aberration even at 25x, and edge clarity remains usable. The reticle is detailed but not overwhelming for target shooting.
Eye relief is safe for .308 recoil, and the eye box is forgiving at mid magnification. At max zoom, it tightens but remains manageable with a proper cheek weld.
Durability is outstanding. I mounted it on an M110 clone using a 20 MOA mount and ran about 300 rounds of 168gr Federal Gold Medal Match—zero never shifted.
Turrets are tactile and precise. I performed a box test at 100 yards, and tracking returned perfectly.
Magnification is ideal for 300–800 yards. Parallax adjustment is smooth and precise.
Mounting requires 34mm rings. I recommend a solid one-piece mount for stability.
From my experience, this scope turns the M110 into a true precision platform. Reddit users often praise its “budget Nightforce” feel.
Verdict: Best for long-range shooters wanting premium-like performance without premium pricing.
