Sun Optics 3-9×40/Shorty Forty II/BDC/Compact Rifle Scope Review

Let’s Dive into Sun Optics 3-9×40/Shorty Forty II/BDC/Compact Rifle Scope

The Sun Optics 3-9×40/Shorty Forty II/BDC/Compact Rifle Scope aims to deliver reliable performance in a compact package. This scope, manufactured by Sun Optics, boasts a Bullet Drop Compensating (BDC) reticle, multi-coated lenses, and durable construction, making it potentially suitable for various shooting applications, from hunting to target practice. Its smaller size and lighter weight also appeal to shooters looking for a streamlined optic.

I was looking for a scope that could offer decent magnification for mid-range shooting without adding excessive weight to my hunting rifle. I wanted something durable enough to withstand the rigors of field use and the BDC reticle was a feature I was interested in exploring for quicker holdover adjustments at different distances.

The scope arrived securely packaged in a gift box. My initial impression was positive, the matte black finish looked clean and the scope felt surprisingly solid for its compact size.

I considered the Vortex Crossfire II 3-9×40 and the Leupold VX-Freedom 3-9×40. Ultimately, the Sun Optics model’s shorter length and the promise of a BDC reticle at a more budget-friendly price point swayed my decision.

I was cautiously optimistic; the price made me wonder about the optical quality, but the compact design and BDC reticle had me intrigued. Could this little scope punch above its weight?

Real-World Testing: Putting Sun Optics 3-9×40/Shorty Forty II/BDC/Compact Rifle Scope to the Test

First Use Experience

My first outing with the Sun Optics 3-9×40/Shorty Forty II/BDC/Compact Rifle Scope was at my local shooting range, zeroing it on my trusty .308 bolt-action rifle. The weather was mild and sunny, a perfect day for sighting in a new optic.

The scope performed reasonably well in the good lighting conditions, providing a clear image at lower magnifications. Adjusting the turrets felt tactile and the clicks were audible, although somewhat mushy compared to higher-end scopes.

It took a few shots to get properly zeroed. However, the adjustments seemed consistent enough.

Extended Use & Reliability

After several weeks of range sessions and a few short hunting trips, the Sun Optics 3-9×40/Shorty Forty II/BDC/Compact Rifle Scope has held zero consistently. The matte finish, however, is showing some minor scratches from brushing against branches in the field.

Despite not being babied, the scope has shown no signs of internal fogging or other performance issues. Cleaning the lenses is straightforward, using a standard lens cloth removes smudges and dirt easily.

Compared to a more expensive Nikon scope I’ve used in the past, the Sun Optics model doesn’t offer the same level of optical clarity or low-light performance. But, for the price, it has performed better than expected.

Breaking Down the Features of Sun Optics 3-9×40/Shorty Forty II/BDC/Compact Rifle Scope

Specifications

• Objective Lens Diameter: 40 mm – This determines the amount of light the scope gathers, influencing brightness and clarity, especially in low-light conditions.
• Magnification: 3 – 9 x – The variable magnification allows for target acquisition at different distances, from close-range to mid-range shots.
• Reticle: BDC Glass Etched Reticle – The Bullet Drop Compensation (BDC) reticle provides holdover points for different distances, aiding in quick and accurate shots without needing to adjust the turrets.
• Tube Diameter: 1 in – A one-inch tube is a common size, offering a good balance of weight and light transmission, and is compatible with a wide range of mounting rings.
• Reticle Focal Plane: Second Focal Plane (SFP) – With the reticle in the Second Focal Plane, its size remains constant as the magnification changes, making it easier to estimate target size at different distances.
• Exit Pupil: 4.44 – 11.5 mm – The exit pupil is the diameter of the light beam exiting the scope; a larger exit pupil allows for easier eye alignment and a brighter image, particularly at higher magnifications.
• Finish: Matte – The matte finish reduces glare and reflections, making it less likely to spook game while hunting.
• Field of View: 4.8 – 15 ft at 100 yds – Field of view is the width of the area visible through the scope at 100 yards; a wider field of view allows for faster target acquisition, especially in close-quarters situations.
• Eye Relief: 3.5 – 4.5 in – Eye relief is the distance between the shooter’s eye and the scope’s eyepiece where a full image is visible; adequate eye relief prevents recoil-related injuries.
• Color: Black – A standard black color is unobtrusive and blends well with most rifles.
• Weight: 15 oz – The lightweight design minimizes added weight to the rifle, preserving balance and maneuverability.
• Adjustment Click Value: 0.25 MOA – Each click of the adjustment turrets moves the point of impact by 0.25 Minute of Angle (MOA), allowing for precise zeroing and adjustments.
• Length: 9.44 in – The compact length makes it suitable for shorter rifles or those where overall weight and bulk are a concern.
• Adjustment Type: MOA – Minute of Angle (MOA) is a common unit of angular measurement used for adjusting the scope’s point of impact.
• Parallax: 100 yds – The scope is parallax-free at 100 yards, meaning there is no perceived shift in the reticle’s position relative to the target when the shooter’s eye moves.
• Illumination Type: Non-Illuminated – The reticle is not illuminated, making it reliable in all lighting conditions without relying on batteries.
• Fabric/Material: Aviation Grade Alluminum, Aircraft Grade Aluminum – The use of aircraft-grade aluminum ensures high strength and durability while keeping the weight down.
• Lens Material: Glass – Glass lenses provide good light transmission and image clarity.
• Optical Coating: Multi-Coated – Multi-coated lenses reduce glare and increase light transmission, resulting in a brighter and clearer image.
• Weather Resistance: Yes – The scope is designed to withstand various weather conditions, enhancing its versatility for outdoor use.

• Fogproof: Yes – The scope is filled with nitrogen or another inert gas to prevent internal fogging in humid or cold conditions.
• Package Type: Gift Box – The gift box packaging suggests a focus on presentation and protection during shipping.
• Magnification Type: Variable – The variable magnification allows the shooter to adjust the zoom level to suit different target distances and shooting scenarios.
• Gun Type: Rifle – The scope is designed specifically for use on rifles.

Performance & Functionality

The Sun Optics 3-9×40/Shorty Forty II/BDC/Compact Rifle Scope performs adequately for its intended purpose, providing a usable sight picture and consistent adjustments. At 3x magnification, the field of view is wide enough for acquiring targets quickly, while 9x offers enough zoom for identifying details at longer distances.

The BDC reticle is a useful feature for quickly compensating for bullet drop, although it requires knowing your rifle’s ballistics to use effectively. The optical clarity is acceptable, but not exceptional; images are clear enough for accurate shooting in good lighting conditions, but become less sharp in low light.

While it doesn’t compete with high-end scopes, it offers reasonable performance for the price. The turret adjustments, while audible, could be more precise and tactile.

Design & Ergonomics

The scope’s compact size and lightweight design make it a good match for rifles where minimizing bulk is important. The matte black finish is practical and reduces glare.

The eye relief is generous enough to avoid scope bite, even on rifles with heavier recoil. The magnification adjustment ring turns smoothly, allowing for easy changes in magnification.

There’s no noticeable learning curve; the scope is easy to mount and use. The focus ring is a bit stiff initially but loosens up with use.

Durability & Maintenance

The aluminum construction seems sturdy, and the IP67 water resistance rating provides some peace of mind in wet conditions. The scope feels well-assembled, and after several weeks of use, there are no signs of internal fogging or mechanical failures.

Maintenance is simple; cleaning the lenses with a lens cloth is all that’s needed to keep the scope in good condition. The matte finish is easy to wipe down.

Based on my experience so far, the scope should last several years with proper care. The Sun Optics reputation for quality construction suggests reasonable longevity.

Accessories and Customization Options

The scope comes with basic lens covers. Aftermarket options include various scope rings to fit different rifle mounting systems.

There are no other readily available customization options specifically designed for this scope. It is compatible with standard one-inch scope rings from various brands.
