Finding the Best Scope For Air Arms S510 Xtra Fac is essential if you want to unlock the full accuracy potential of this high-end PCP air rifle for target shooting.

Detailed Reviews

Arken Optics SH4 GEN2 4-16X50 Rifle Scope FFP

Arken Optics SH4 GEN2

This is one of my favorite budget precision scopes for PCP rifles like the Air Arms S510 Xtra FAC. Mounted using 30mm medium rings on a dovetail-to-Picatinny adapter, I zeroed this scope at 50m in just 12 shots.
Product Specs
Magnification: 4-16x
Objective: 50mm
Tube: 30mm
Reticle: FFP VPR
Parallax: Side focus
Pros
True FFP reticle at budget price
Excellent turret tracking
Solid build quality
Cons
Slightly heavy
Illumination could be brighter
Glass clarity is impressive for the price. Edge-to-edge sharpness is strong, with minimal chromatic aberration even at 16x. The FFP reticle is ideal for holdovers when shooting varying pellet trajectories.
Eye relief sits around 3.5 inches and feels forgiving. The eye box remains usable even at higher magnification, which is critical when shooting from benchrest positions.
Durability is excellent. After 500+ shots, zero remained stable. The aluminum body feels robust and weather-resistant.
Turrets offer crisp 0.1 MIL clicks. I performed a box test at 50m and tracking returned perfectly to zero.
Magnification range is ideal for 25–100m shooting. Parallax adjusts down to 10 yards, making it perfect for air rifle use.
Mounting was straightforward, and the included accessories are decent for the price.
From my experience, this scope transformed my S510 into a consistent 10-shot group performer at 50m. Online discussions often praise its tracking reliability, especially compared to pricier scopes.
Verdict
A top-tier budget precision scope that punches far above its price.

Turrets are functional but not premium. Clicks are audible but slightly soft.
Magnification is excellent for precision work at 100m. Parallax works down to air rifle distances.
Mounting is easy due to 1-inch tube compatibility.
Personally, I used this for 100m pellet testing and appreciated the extra magnification for spotting hits.
