Vortex Viper HS 1-4x24 Optic
I don’t know who was the first manufacturer to produce a lightweight, low-powered variable optic. Regardless of who was the first, there are now several companies that offer lightweight optics in the 1-4 magnification range - a few that come to mind: Schmidt & Bender Short Dot, Leupold CQBSS, Trijicon Accupoint and US Optics SN-4S. These manufacturers are known for producing high quality, durable scopes that you can take into combat. They aren’t cheap however, ranging from $700 on the low end (Accupoint) to $3700 on the high end (CQBSS).
Vortex Optics, a family-owned company based in Middleton, WI has been around since 1986, but in the last few years, they have expanded their product line and experienced a surge in popularity among hunters and target shooters, offering scopes with high-end glass in their Viper line and above.
Of those new offerings is the Viper HS and the Viper PST, 1-4x24mm. Vortex offers a nice discount for military/law enforcement personnel, but when I dropped by their storefront to procure one, I was told these very popular scopes are back-ordered about two months. I was able to find an HS in stock at Brownell’s for $440. I mounted it to my rifle with a 30mm LaRue SPR-E (extended eye relief) mount as I generally shoot my ARs nose to charging handle. Quick release levers are a must for an optic like this on a duty rifle, should anything happen to the glass that would make it impossible to see through. For now, this is being used only as a 3-gun rifle, otherwise I would certainly have BUIS mounted as well.
The lenses in the Viper line of scopes are fully multi-coated, extra-low dispersion glass. Extra-low dispersion lenses are generally something only found in higher-end optics, usually costing several hundred dollars more than the Vortex Vipers. This leads to excellent color quality, high resolution, minimal distortion, and high light transmission. I spent some time this week still-hunting for deer with this rifle, and was impressed with how bright the images were in dark, pine forests, or at dusk. The optic is waterproof and filled with Argon gas, guaranteed not to fog.
The difference between the HS and PST is the PST has exposed target turrets, whereas the HS has capped turrets. The HS features 1/2 MOA turrets that click crisply when turned. Personally, I don’t believe exposed target turrets are really a necessity on this type of optic - I think in a combat environment, you’d be faster and better served simply knowing your holdovers and using the reticle subtensions. I generally leave the turrets capped so they don’t get moved accidentally, but they are there if you want them. The HS turrets also have a convenient quick-zero feature, allowing you to adjust your zero without having to dink around with set screws to remove the turrets.
The magnification ring is marked with several power settings, as well as a “reticle multiplier,” which provides an integer to allow calculation for bullet drop or range while using the reticle subtensions at different powers. Again, something I will probably never use, but it’s a thoughtful feature that doesn’t add weight or take up space. Another nifty feature is the raised magnification indicators - visible without having to move your head from behind the rifle. A fiber optic rod makes it easy to see your magnification setting. I found the ring itself to be a little stiff to adjust - especially while wearing gloves. Good that it will stay put, but not especially fast. I added an MGM throw-lever which is fairly low-profile, and makes changing the magnification on the optic much faster.
The reticle is a simple MOA scale, marked in 2 MOA increments, with a one MOA dot in the center. Surrounding the center dot are four semi-circles, which form a ring 22 MOA wide. This provides a precise aiming point for long range, or precision shooting, but is also extremely fast on close targets. It has everything you need - and nothing you don’t, which leads to a simple, uncluttered view.

One note about the photos - with proper eye relief, the tube does not appear to be so thick.
That effect is simply from me failing to maintain proper eye-relief with the camera.

The illumination control has 10 settings, with an off position between each brightness level. Levels 1-5 are for use with night vision, 6-10 provide illumination for the naked eye. The reticle is powered by one, CR2032 battery. I have not had the opportunity to test battery life.
My biggest complaint, which is the complaint I have with really all of the optics in this class is the maximum brightness setting is simply not bright enough to see on a sunny day. It more than capable of performing in low light condition and overcast skies, but when the sun peeks out, forget it. Of course, you still have the the black reticle, which works well without illumination - so long as your targets are not all black. That said, if Vortex were able to add brighter illumination to the center dot and/or reticle “rings” - in line with an Aimpoint or EoTech RDS, this optic would be unstoppable. For now, the illuminated reticle is similar to that you’d find on a traditional sniper scope.

When putting rounds downrange, I found the optic to be more than adequate to locate and engage targets up to 500m away. At that range, I was limited only by the weapon platform and the 55gn ball ammo I was shooting. The MOA subtensions made holdovers easy once I figured my dope, and while I still question their real-world practicality, on the flat range the target turrets made for easy, first-shot hits on 12" plates out to 400m. After dozens of adjustments, the turrets always returned my 100 yard zero dead-on. The parallax is non-adjustable and fixed at 100 yards, so carefully centering the reticle in the tube is important when engaging targets at long range.
Up close, the optic provided easy target acquisition and transitions. The 22 MOA circle was easy to pick up when blazing from target to target. I didn’t notice any distortion or fish-eye effects and was able to shoot with both eyes open without much adjustment from a traditional red dot sight. Unlike red dot sights, where the red dot is “focused” on infinity, it is possible to let your eye focus on the reticle and not the target at close range. You need to spend some time shooting any new optic before you deploy it in the field, and this is no exception. On 1x magnification, it is similar, though not identical to the feel of a red dot. I also found that mounting your scope in a position to provide a consistent cheek weld and eye-relief is extremely helpful - again, why I chose the LaRue SPR-E mount and shoot nose-to-charging handle.

Overall, I am really impressed with this optic. It combines high quality glass with well thought out features and an unequaled warranty at an excellent value. Aside from the lack of higher illumination settings, the Vortex Viper 1-4x24 HS can do everything a red dot sight and a magnifier can do - and more - in a lighter, slimmer package.
For now, it will remain on my three-gun rifle, and available for home defense. Owning a rural property bring forth the possibility of needing a flexible long gun for both close quarters as well as longer-range shooting, and I think this optic will cover those bases. I’m very demanding of my work equipment, and wouldn’t hesitate to put this optic on a duty rifle, should our department make the necessary policy changes to allow variable-powered optics. Several snipers on my department have been given permission to mount the Viper 1-4x24 PST on their AR-15s, should they need a little extra reach in a patrol environment.
