Finding the Best Scope For 400 Yards requires balancing optical clarity, precise turret adjustments, and reliable magnification that allows accurate target acquisition at mid-to-long ranges. In my experience shooting with rifles such as an AR-10 chambered in .308 Win (168 gr match ammo) and a bolt-action .223 Rem platform, a scope designed for this range must deliver crisp image quality, repeatable tracking, and a forgiving eye box. A properly designed optic also ensures quick zeroing, dependable holdovers, and confidence during real-world shooting conditions like wind, low light, and extended range sessions. In this guide, I’ll review six scopes that consistently perform well around the 300–500 yard mark, based on hands-on experience, technical evaluation, and community feedback.

Arken Optics EP5 5-25X56 Rifle Scope FFP
The EP5 is one of the most popular mid-priced precision scopes among long-range shooters. I mounted it on an AR-10 platform using a 20 MOA one-piece mount and tested it with .308 Win 168-grain match ammo. The large objective lens and generous magnification range make it extremely capable for targets between 200 and 800 yards.
Product Specs
- Magnification: 5-25x
- Objective Lens: 56mm
- Tube Diameter: 34mm
- Reticle: FFP VPR MIL
- Turret Adjustment: 0.1 MIL
- Parallax: Side focus
Pros

Glass clarity is impressive with excellent edge-to-edge resolution. While testing during midday sun and late dusk sessions, I noticed minimal chromatic aberration and very good contrast. At 25x magnification the image remained sharp enough for spotting steel plates at 600 yards.
Eye relief is comfortable and measures roughly 3.5 inches. The eye box remains forgiving even at mid-range magnification settings, which helps during rapid follow-up shots.
Durability is one of the strongest points of this scope. The aircraft-grade aluminum body handled over 400 rounds of .308 without losing zero.
The elevation and windage turrets feature tactile clicks with excellent feedback. I conducted a box test and tracking returned precisely to zero.
Magnification range is ideal for the 400-yard zone because it allows both wide field-of-view and precise target identification.
Mounting was simple with standard 34mm rings and barrel clearance was perfect on my setup.
During my personal testing, the rifle required about eight shots to zero at 100 yards. After extended shooting sessions, the scope held zero consistently.
Many shooters on Reddit forums praise the EP5 for delivering “premium-level tracking without the premium price.”
Verdict: This scope is an outstanding option for precision shooters who regularly engage targets between 300 and 800 yards.

How to Choose the Right Scope for This Pistol
Selecting the right scope for 400-yard shooting requires careful evaluation of several technical factors. Magnification is one of the most important elements. While extremely high magnification might seem appealing, many shooters find that a 4-16x or 5-25x range provides the ideal balance between field of view and target detail.
Optical clarity is equally critical. High-quality glass ensures targets remain sharp even under challenging lighting conditions. Look for scopes with fully multi-coated lenses and large objective diameters such as 44mm or 56mm.
Reticle design also matters. First focal plane reticles scale with magnification and allow accurate holdovers at any zoom level. This feature is especially useful for longer distances where bullet drop and wind drift must be compensated.
Turret quality is another crucial factor. Accurate and repeatable adjustments allow shooters to dial elevation confidently. I always perform a box test to verify turret tracking before trusting a scope in the field.
Eye relief and eye box comfort affect usability as well. A forgiving eye box allows faster target acquisition and reduces fatigue during extended shooting sessions.
Finally, durability should not be overlooked. A scope used for mid-to-long range shooting must withstand recoil, environmental conditions, and long-term use without losing zero.
FAQs
What magnification is best for 400-yard shooting?
Most shooters find that magnification between 10x and 16x works very well for targets at 400 yards.
Is a first focal plane scope better for long-range shooting?
Yes. FFP reticles allow accurate holdovers regardless of magnification.
Do I need a 56mm objective lens?
Not necessarily, but larger objectives improve light transmission.
How important are turret adjustments?
Extremely important. Accurate turrets ensure repeatable elevation adjustments.
Can an LPVO work at 400 yards?
Yes. LPVO scopes with 6x–8x magnification can perform well with proper reticle holdovers.
