Arken Optics SH4 GEN2 4-16X50 Rifle Scope FFP
This scope is my go-to recommendation when someone asks for a serious budget precision optic. Mounted on my Swiss K31 using a 20 MOA rail and 30mm rings, it delivered consistent results out to 600 meters.
Product Specs
- Magnification: 4-16x
- Objective Lens: 50mm
- Tube: 30mm
- Reticle: FFP VPR
- Turrets: 0.1 MIL
Pros
- Excellent tracking accuracy
- Clear glass for the price
- True FFP reticle
Cons
- Slightly heavy
- Illumination not very bright
The glass clarity is impressive at mid magnification, with minimal chromatic aberration. Edge-to-edge clarity is good, though slight softness appears at 16x.
Eye relief sits around 3.5 inches, and the eye box is forgiving at lower magnifications but tightens at max zoom.
Durability is excellent. After 400 rounds of 7.5x55 Swiss, the zero held perfectly.
Turrets are tactile and precise. I performed a box test and confirmed accurate return to zero.
Magnification range suits 100–600m target shooting, and side parallax adjustment is smooth.
Mounting was straightforward, though the scope’s weight requires solid rings.
From my experience, this scope punches far above its price. Reddit users often praise its tracking reliability, though some mention weight concerns.
Verdict: Best budget precision optic for the K31.

How to Choose the Right Scope for This Pistol
Choosing the right optic for a Swiss K31 requires understanding both the rifle’s strengths and your shooting goals. The K31 is inherently accurate, often capable of sub-MOA groups with quality ammunition like 168gr match loads. That means your scope must support precision rather than limit it.
First, magnification matters. For target shooting, I recommend at least 9x on the high end, but ideally 12x–16x if you’re shooting beyond 300 meters. Higher magnification helps with precise aiming but can reduce field of view and eye box forgiveness.
Second, consider focal plane. First focal plane (FFP) scopes allow accurate holdovers at any magnification, which is useful for dynamic target shooting. Second focal plane (SFP) scopes are simpler and often cheaper but require consistent magnification for accurate holds.
Turrets are another critical factor. If you plan to dial for elevation, look for tactile, repeatable turrets with clear click values (0.1 MIL or ¼ MOA). Budget scopes can vary widely here, so this is where hands-on testing matters.
Glass quality is often overlooked but essential. Clear glass with minimal distortion improves target identification and reduces eye strain during long sessions.
Mounting is especially important for the K31 due to its straight-pull bolt design. Ensure your mount provides proper clearance and maintains alignment.
Finally, durability and warranty should not be ignored. Even budget scopes should hold zero after hundreds of rounds.
