Detailed Reviews
Hawke Vantage 3-9x40 AO IR
The Hawke Vantage is purpose-built for air rifles, which makes it an outstanding match for the Air Arms S400 MPR. It balances affordability with features typically found in more expensive optics.
Product Specs
Reticle: Mil Dot illuminated Parallax: Adjustable objective Pros
Designed specifically for airgun recoil Illuminated reticle helps in low light Smooth parallax adjustment Cons
Illumination not very bright in daylight The glass clarity is surprisingly sharp for the price. I noticed minimal distortion, and edge clarity remains usable even at 9x. The mil-dot reticle is ideal for holdovers in airgun shooting where pellet drop is significant.
Eye relief feels comfortable at around 3.5 inches, and the eye box is forgiving—perfect for bench shooting sessions. Durability is excellent, especially considering Hawke’s airgun reputation.
The turrets are not designed for constant dialing, but they track reliably when needed. Magnification is ideal for 25–75 meter target shooting, and the adjustable objective is a must-have for air rifles.
Mounting was straightforward using standard rings, and it paired perfectly with my S400 MPR. Personally, I found zeroing took about 15 shots, and it held zero flawlessly after 500 pellets.
Online discussions often highlight Hawke as the go-to brand for PCP rifles, and I agree. It simply works.
Verdict: Best all-around option for serious target shooters on a budget.
UTG 3-9x32 BugBuster AO

Smaller objective limits brightness Slightly stiff adjustments Glass clarity is good, especially for its size. It performs best in daylight conditions. The reticle is clean and useful for precise holdovers.
Eye relief is generous, and the eye box is forgiving—ideal for quick target acquisition. Durability is excellent; UTG scopes are known to handle recoil and vibration well.
Turrets are tactile enough, though not premium. Magnification is perfect for airgun ranges, and parallax adjusts down to very close distances.
In my experience, this scope shines on compact setups. On the S400 MPR, it kept the rifle balanced and easy to handle.
Forum users consistently praise its reliability and value.

How to Choose the Right Scope for This Pistol
Choosing the Best Scope For Air Arms S400 Mpr depends heavily on your shooting style and distance. For target shooting, clarity and parallax adjustment are more important than extreme magnification.
First, always prioritize adjustable parallax. Air rifles operate at shorter distances, often between 10 and 50 meters. Without proper parallax adjustment, your accuracy will suffer due to reticle shift.
Second, consider magnification range. For most S400 MPR users, 3-9x or 4-16x is ideal. Higher magnification can help with precision, but it also narrows your field of view and tightens the eye box.
Third, look at reticle design. Mil-dot reticles are excellent for airguns because they allow easy holdover adjustments for pellet drop. This is crucial since pellets lose velocity quickly.
