Technical Aspects

Below are the primary components to consider when choosing between the 6-24×50 and the 4-16×44 Viper rifle scopes. The technical elements will make short work of your long-range shooting targets and tactical practice runs. That being said, a closer look at these aspects can help you decide which scope will best suit you and your specific needs.

Zoom and Magnification Ranges

Choose from 6-24x or 4-16x magnification depending on your specific needs. You’ll pay a bit more for the 6-24×50 but it is well worth it for the versatility. Long-range rifles such as the .308 – check out our best .308 scopes – will love the Viper HST’s ability to easily switch between zoom magnifications, granting you a precise vision for those long-distance shots. The Precision-Glide Erector System makes clean transitions through the zoom lenses for seamless magnification.

Available Reticles

The scopes’ second focal plane reticles are hashmark-based for great versatility and accuracy during hunting situations. This allows you to maintain the appearance of your target at different distances. The subtensions work great for estimating range while taking wind drift into account for more precise shooting. This comes in handy during both tactical and long-range hunting scenarios.

Field of View

The 6-24×50 field of view is 17.8-5.1 feet at 100 yards while the 4-16×44 is 27.4-7.4 feet at 100 yards. It is not a huge difference so choose the scope that best suits your overall needs. The field of view for the 4-16×44 will serve you well, especially with additional features such as ArmorTek protection against dirt, oil, and scratches. Also, the lenses are purged with argon gas to make them fogproof while the O-ring seals keep moisture out. This makes for a great scope in all kinds of weather conditions.

Considering a Leupold scope for your .308? Here are the reviews of the top-rated optics from Leupold for the .308!

Eye Relief

Both Viper scopes have a 4.0” eye relief, which is an ample size for hunters of all abilities and skill levels. It is particularly nice because you don’t run the risk of the gun recoiling and hitting your face. With four inches of leeway, you can protect your eye while still getting a good view of your target.

Objective Lens Size(s)

Depending on the model you choose, you will have an objective lens of either 50mm or 44mm. The latter is quite common in medium-range hunting rifle scopes, although 50mm and larger are becoming more popular. The nice thing here is that choosing a larger objective lens won’t cause more light to transmit through. It might also make the scope more comfortable to work with; again, this depends on overall ability and skill level.

Tube Diameter

Both scopes have a 30mm tube body made of durable aluminum. The single-piece design allows for better internal adjustment as well as a sleeker look. You also get the advantage of better alignment for your target visuals. The tube is reinforced with a hard anodized finish and the matte surface won’t give off much glare, making it ideal for camouflage.

Light Transmission

The 6-24×50 and 4-16×44 have extra-low dispersion glass for images with higher fidelity and resolution. The XR fully multi-coated proprietary lenses are anti-reflective and increase overall light transmission. Both scopes come with a four-inch sun shade and protective lens cap. The 6-24×50 will give you a bit more light through the objective lens.

Turrets and Adjustments

The tactical turrets on the 6-24×50 and 4-16×44 have ¼ MOA adjustment graduation and 12 MOA travel per rotation. Where they differ is in the maximum elevation and windage adjustments. The 6-24×50 maxes out at 65 MOA while the 4-16×44 reaches 75 MOA. Both have a fiber optic turret rotation indicator to provide a point of reference and the exposed turrets make for quick, easy accuracy adjustments.

Parallax Settings and Adjustments

Both scopes offer a parallax setting of 50 yards to infinity with side focus adjustments conveniently on the left side of the turret. This makes accessibility safe and easy while helping you get the optimal image focus for your tactical or long-range shots. The Precision-Force Spring System makes for simple adjustments and maximum repeatability, which allows you to make more shots in less time.

Overall, these Viper rifle scopes will serve you well for long-range shooting or tactical scenarios. With their large magnification and zoom ranges, you can take them along for a variety of practice rounds. They’re not the most lightweight but they aren’t too heavy either so they can accompany your shooting rifle just fine.

While these scopes are great for longer distances, you don’t want to rely on them for shorter-range shots. Their magnification ranges and hashmark-based reticles are meant for longer distances and allow you to hold on to an accurate target even with that extended range. Plus, the tactical-style turrets with ¼ MOA increments make reading elevation and windage adjustments a breeze. As the name Viper HST suggests, you will want to use this for tactical shooting or hunting at long distances.
