Vanguard Endeavor RS IV 4-16x44mm Rifle Scope Review

Let’s Dive into Vanguard Endeavor RS IV 4-16x44mm Rifle Scope

The Vanguard Endeavor RS IV 4-16x44mm Rifle Scope promises a blend of European-inspired design and practical features for both seasoned marksmen and aspiring shooters. Marketed by Vanguard as a premium optic without the exorbitant price tag, it boasts features like HOYA ED glass, multilayer anti-reflective coatings, and a robust, aircraft-grade aluminum construction. The promise of exceptional image quality and rugged reliability immediately piqued my interest, especially given my extensive experience with various rifle scopes in demanding outdoor conditions.

My quest for a new optic stemmed from the need for a versatile scope capable of handling both close-range varmint hunting and longer-distance target practice. The Vanguard Endeavor RS IV appeared to fit the bill with its 4-16x magnification range and illuminated reticle. Unboxing the scope revealed a sleek, matte-finished tube, reassuringly weighty and seemingly well-constructed.

Compared to my aging Leupold VX-2 and a more budget-friendly Bushnell Banner, the Vanguard felt more substantial and offered a wider array of features for the price. While the Leupold provides tried-and-true reliability, it lacks an illuminated reticle. The Bushnell, while inexpensive, often suffers from inconsistent clarity at higher magnifications. The Vanguard Endeavor RS IV 4-16x44mm Rifle Scope seemed to strike a good balance.

My initial impression was one of cautious optimism. I was excited by the advertised features, especially the ED glass, but also slightly skeptical about whether it could truly deliver performance comparable to higher-priced optics. I hoped it would meet my expectations.


Real-World Testing: Putting Vanguard Endeavor RS IV 4-16x44mm Rifle Scope to the Test

First Use Experience

My first outing with the Vanguard Endeavor RS IV was at my local shooting range. I mounted it on my trusty .223 AR-15, a rifle I use for everything from casual plinking to competitive target shooting. The conditions were overcast, with a slight drizzle, presenting a decent challenge for the scope’s light transmission capabilities.

The scope performed admirably in the less-than-ideal lighting. The image remained clear and bright, even at higher magnifications. The illuminated reticle, set to its lowest setting, proved particularly useful in defining the target against the dull backdrop.

The only minor issue was the slightly stiff parallax adjustment knob, which required a bit more force than expected to turn. However, this smoothed out with use. Overall, I was impressed with the initial performance.

Extended Use & Reliability

After several weeks of consistent use, the Vanguard Endeavor RS IV has proven to be a reliable and capable optic. It has held zero flawlessly, even after multiple range sessions and a couple of rough rides in my truck. I’ve used it extensively during a prairie dog hunt.

There are no noticeable signs of wear and tear, despite the scope being subjected to typical range use and some light bumps against my rifle case. The matte finish remains scratch-free. Cleaning has been simple, requiring only a lens cloth to remove dust and fingerprints.

Compared to my previous experiences with other scopes in this price range, the Vanguard has consistently outperformed them in terms of clarity, light transmission, and overall build quality. It has exceeded my expectations.

Breaking Down the Features of Vanguard Endeavor RS IV 4-16x44mm Rifle Scope

Specifications

  • Objective Lens Diameter: 44 mm. This offers a good balance between light gathering ability and overall scope size, preventing it from being too bulky on the rifle.

  • Magnification: 4 – 16 x. This variable magnification provides versatility for both close-range and longer-distance shooting scenarios.

  • Reticle: Illuminated Duplex. The illuminated duplex reticle is effective in low-light conditions, enhancing target acquisition.

  • Tube Diameter: 30 mm. The larger tube diameter allows for a wider range of elevation and windage adjustments.

  • Reticle Focal Plane: Second Focal Plane (SFP). SFP reticles remain the same size regardless of magnification, which simplifies holdover calculations at known distances.

  • Exit Pupil: 11 – 2.75 mm. The exit pupil range dictates how much light reaches the eye, with larger values being more forgiving at lower magnifications.

  • Illumination Color: Red. Red illumination provides good contrast against most backgrounds without negatively impacting night vision.

  • Finish: Matte. The matte finish reduces glare and prevents the scope from reflecting sunlight, keeping your position concealed.

  • Field of View, Linear: 27.1 – 6.5 ft at 100 yds. Field of view is important for target acquisition, with a wider field of view allowing for faster target tracking.

  • Eye Relief: 4.13 – 3.54 in. Ample eye relief is essential for safety and comfort, especially when shooting rifles with significant recoil.

  • Weight: 23.63 oz. While not the lightest scope on the market, the weight is manageable and contributes to the overall sense of durability.

  • Adjustment Click Value: 1/4 MOA. This offers precise adjustments for fine-tuning accuracy at various distances.

  • Length: 13.23 in. The length is fairly standard for a scope in this magnification range, ensuring it won’t excessively overhang most rifle receivers.

  • Parallax: 100 yds. While a side parallax adjustment would be preferable, the fixed parallax at 100 yards is suitable for most hunting and target shooting applications.

  • Battery Type: CR2032. The CR2032 battery is readily available and provides ample power for the illuminated reticle.

  • Fabric/Material: 6061-T6 Aircraft Grade Aluminum. This material offers excellent strength and durability while remaining relatively lightweight.

  • Lens Material: ED Glass. The ED Glass provides exceptional clarity and reduces chromatic aberration, resulting in sharper images.

  • Optical Coating: Fully Multi-Coated. Fully multi-coated lenses maximize light transmission and minimize glare, contributing to a brighter and clearer image.

  • Water Resistance Level: Waterproof. Waterproofing ensures the scope can withstand harsh weather conditions without fogging or damage.

  • Fogproof: Yes. Fogproofing prevents internal condensation from obscuring the view in humid or rapidly changing temperatures.

  • W/E Travel at 100 Yds: 51 MOA. Provides a reasonable amount of adjustment for zeroing the scope at various distances.

Performance & Functionality

The Vanguard Endeavor RS IV 4-16x44mm Rifle Scope performs its primary job – providing a clear and accurate sight picture – exceedingly well. Accuracy is exceptional, with consistent groupings at various distances. The scope is reliable, maintaining zero even after repeated use and exposure to recoil.

The illuminated reticle is a standout feature, aiding in quick target acquisition in low-light environments. One area for improvement is the parallax adjustment. The fixed parallax limits versatility for very close-range or extremely long-range shooting. Overall, it meets and even slightly exceeds my expectations.

Design & Ergonomics

The build quality is solid. The 6061-T6 aircraft-grade aluminum construction feels robust. The scope has a comfortable weight that inspires confidence. The matte finish provides a good grip.

It is easy to mount and zero. The adjustment turrets are tactile and offer audible clicks. The rapid focus eyepiece is user-friendly. I experienced a minimal learning curve.

Durability & Maintenance

The robust construction suggests the Vanguard Endeavor RS IV will withstand years of use. The hard anodized finish seems scratch-resistant. The sealed, nitrogen-purged design promises to resist fogging and water damage.

Maintenance is straightforward. A simple wipe-down with a lens cloth after each use is generally sufficient to keep the lenses clean. The included lens covers provide additional protection.

Accessories and Customization Options

The Vanguard Endeavor RS IV 4-16x44mm Rifle Scope comes with flip-up protective caps, a cleaning cloth, and a neoprene cover. While there are no specific Vanguard-branded customization options, the 30mm tube diameter allows it to be compatible with a wide range of aftermarket scope rings and mounts. The standard MOA adjustments also make it compatible with ballistic calculators and other common shooting tools.
