Arken Optics EP8 1-8x28 LPVO First Focal Plane Riflescope
The Arken EP8 is one of the most versatile LPVOs I’ve mounted on my S&W M&P 15. Built with a robust 34mm tube and first focal plane reticle, it bridges close-quarters speed with mid-range precision exceptionally well.
Product Specs
- Magnification: 1-8x
- Objective Lens: 28mm
- Tube: 34mm
- Reticle: FFP illuminated
- Turrets: Tactical locking
Pros
- Excellent edge-to-edge clarity
- True 1x performance
- Durable construction
Cons
- Slightly heavier than competitors
- Illumination not daylight-bright in harsh sun
The glass clarity is impressive for its price class, with minimal chromatic aberration. I noticed only slight edge distortion at 8x, which is acceptable. The reticle scales perfectly thanks to FFP, making holdovers intuitive.
Eye relief is forgiving at around 3.5 inches, and the eye box is generous even at higher magnification. This makes fast transitions between targets smooth.
Durability is outstanding. I ran this on a 5.56 NATO 62gr setup for over 500 rounds, and it held zero perfectly—even after some rough handling.
The turrets have crisp tactile clicks (0.1 MIL), and I confirmed tracking accuracy with a box test. Adjustments returned precisely to zero.
In my experience, mounting on a 30 MOA cantilever mount was straightforward, and zeroing took about 10 rounds at 100 yards.
Online discussions praise its value, especially comparing it to higher-end optics.
Verdict: A top-tier LPVO for serious shooters wanting performance without premium pricing.

How to Choose the Right Scope for This Pistol
Choosing the right scope for your S&W M&P 15 depends heavily on your intended use. If you primarily shoot within 100 yards, a low-power variable optic (LPVO) with 1-4x or 1-6x magnification is ideal. For more versatile shooting, especially out to 500 yards, a 1-8x or even 1-10x scope provides better flexibility.
First, consider focal plane. First focal plane (FFP) scopes are better for precision shooting because the reticle scales with magnification. Second focal plane (SFP) scopes are simpler and often more affordable, making them suitable for general use.
Next, evaluate glass quality. Clear optics reduce eye strain and improve target identification. Look for minimal chromatic aberration and strong edge-to-edge clarity.
Eye relief and eye box are critical for AR platforms. A forgiving eye box allows faster target acquisition, especially in dynamic shooting scenarios.
Durability is also key. Your scope should withstand recoil, environmental conditions, and rough handling. Look for aircraft-grade aluminum construction and waterproof ratings.
Finally, consider reticle design. BDC reticles are great for beginners, while MIL or MOA reticles offer more precision for experienced shooters.
