5 Best Scope for Bullpup Air Rifle (2025 Review & Field Test Guide)

Finding the best scope for bullpup air rifle can be a unique challenge. Bullpup designs—like the FX Impact, Daystate Red Wolf, or Hatsan BullBoss—have shorter overall lengths and more compact balance points.
This means your optic must be not only lightweight but also provide clear sight pictures, generous eye relief, and precise parallax control for airgun distances.
Over years of field testing from pest control to bench shooting, I’ve tested dozens of optics to determine which ones truly perform on bullpup PCP platforms.
Below, I’ll share my personal experience with several leading optics, complete with detailed performance notes, online feedback, and technical analysis to help you pick the perfect companion for your bullpup rifle setup.

Top Product List: 5 Best Scope for Bullpup Air Rifle of 2025

1. Arken Optics EPL4 FFP Illuminated Reticle

The Arken EPL4 is an outstanding mid-range optic perfectly suited for powerful PCP bullpup rifles. Its first focal plane (FFP) reticle and robust aluminum build make it ideal for airgun precision from 25 to 150 yards.
Product Specs:
Magnification: 6-24x50mm
Focal Plane: FFP
Reticle: VPR MIL reticle, illuminated
Tube: 30mm
Weight: 24.8 oz
Parallax: 10 yards to infinity
Pros:
Excellent edge-to-edge clarity
True 10-yard parallax
Positive turret feedback
Lifetime warranty
Cons:
Slightly heavy for ultralight bullpups
No zero stop
Glass Clarity & Reticle The VPR reticle is fine and highly detailed, ideal for long-range pellet flight correction. Glass clarity ranks close to Vortex Viper PST levels—bright, contrasty, and well-coated against glare.
Eye Relief & Eye Box Generous eye relief at ~3.5" suits bullpup rifles, which often require flexible mounting due to rearward breech positioning.
Durability I mounted it on an FX Maverick .25 cal using a 30mm one-piece mount. After 300 shots, zero retention was perfect even with repeated adjustments.
Elevation & Windage Knobs The 0.1 MIL turrets are tactile with distinct clicks. My box test results were dead on—each click tracked exactly as marked.
Magnification & Parallax The parallax adjustment from 10 yards is excellent for close airgun work, something most centerfire scopes overlook.
Mounting & Accessories I recommend a medium-profile 20 MOA mount for PCP rifles to maintain a comfortable cheek weld.
Personal Experience At 50 yards, I could consistently print sub-MOA groups. The illuminated reticle is daylight-visible, making it versatile for hunting squirrels or pigeons under variable light.
Online Feedback Reddit users on r/Airguns often call the EPL4 “the poor man’s Vortex Razor,” praising its optical performance and tracking repeatability.
Verdict: A premium choice for serious airgunners who demand FFP precision on their bullpup setups.
