Preface
As the shooting sport optics market continues to grow, it can be challenging to keep up with all the options. I try to keep informed on so many of the optics manufacturers, but admittedly it can be challenging at times. Today I bring you another optics brand that is new to me called Discovery Optics, oddly shortened then lengthened again to DiscoveryOpt Optics. Like some other Asian optics companies, DiscoveryOpt offers a variety of riflescopes at surprisingly affordable prices. According to the company’s mission statement, they seek to deliver scopes that rival the worlds best at factory direct prices. In order to evaluate this proposition, I present for you today a review of the DiscoveryOpt ED-PRS 5-25X56 Gen 2 Riflescope. I spotted these optics on display at the final Snipers Hide Cup at Rifles Only, and I was interested enough to give a closer look.
DiscoveryOpt Optics
Discovery Optics has a broad line of products, composed of just about every type of optical sight type you can imagine. It seems many Asian optic manufacturers start out their product lines based on what they see in movies. We have all seen the memes of Temu scopes stacked with ridiculous levels of bells and whistles. Yet the quality of any one of those features is questionable.
Discovery Optics seems to have moved past that, though browsing their website I still see some interesting products. But they also have done a very good job at emulating proper products that I wanted to try out. That is where the ED-PRS 5-25X56 Gen 2 riflescope comes in, on paper it boasts most the of desirable features we precision rifle junkies are after.
The DiscoveryOpt PRS Gen 2
When the box arrived, I was quick to open it. Quality packaging protected this scope, with a foam-lined box. Inside the box I found a selection of included accessories:
- The ED PRS Gen 5-25X56 scope
- A sunshade
- Ocular and objective flip caps
- A lens cloth
- Manual and Spec card
- Tool for adjustment
- A lens pen
- A scope leveling tool
I unpacked everything, and was quickly impressed with it all. The scope itself seemed really large, its turrets might be the largest of any riflescope I’ve ever used. The turrets are adjusted with no tools needed, you can remove them using only your fingers (all five of them if you want). The control surfaces have a nice texture to them, and they included a removable throw-lever on the magnification ring.
My initial inspection running the turrets and other controls up and down confirmed everything worked as designed. The reticle illumination fired on command, illuminating only the center of the reticle out to 1 MRAD. Parallax adjustment went from 25, 50, 100, 200, 500, Infinity. I spun on the shade, which made a flawless transition on the objective. Just for fun I installed the flip caps which were also pretty nice, they looked similar to Tenebraex caps but likely not as tough. After a few more minutes tinkering, it was time to mount this scope and see how it worked with a rifle.
Specifications
Mounting
I decided to mount the Discovery scope in my one-piece Anubis Defense scope mount. It too is a bit overbuilt and robust so I figured it would match. Leveling the scope was easy using the scope leveling tool included by DiscoveryOpt. There is a baseplate and a wedge you can use to ensure the bottom of the scope housing is perfectly parallel. It’s really a nice little tool, and can be used to setup scopes in a variety of configurations. It will definitely be staying in my toolbox.
I intended to mount the scope on my Desert Tech SRS M2, where I do a lot of my scope testing. This rifle makes it extremely easy to swap scopes around, and has very predictable accuracy to evaluate the scope performance.
Zeroing Turrets and Zero-Stop
After zeroing the scope to the rifle, it was time to slip the turrets back to zero. This is very easy using the finger secured turret caps. Just spin them loose and lift them off the inner hub. You can set the turrets back to zero, and snug the caps back in place.
Setting the zero-stop is easily done during this process as well, using the provided tool. Loosening the screw that clamps the stop to the turret hub, you can slide it down against the base of the housing, and turn it clockwise against the stop lug. With the stop in place you snug the screw back up, and reinstall the turret.
With the turret zeroed, and the zero-stop set I was in business. Part of the reason I used my SRS M2 for this review is because I have exhaustive experience shooting it. The dope I have for the 6mm GT barrel is as predictable as the sunrise, so it would be perfect for testing the performance of the DiscoveryOpt PRS Gen 2 Scope.
Shooting the PRS Gen 2
My initial concerns about the eye-box being to tight weren’t warranted. By that I mean it was a little touchy getting perfect eye relief for a concise image, but once I got on the rifle it was much easier. With the rifle setup the way it fits me, I didn’t even really notice the slightly tighter eye-box. My experience has shown me that less expensive scopes tend to be touchy like that.
I moved to shooting from a 100 yard distance to a much wider canyon area. This allowed me to shoot as far as I dared, but for starters I picked out a small patch of snow sitting on a rock at 405 yards. I dialed my correction, and fired a shot that would scatter the snow.
Both at the range and in the field I found the DiscoveryOpt ED-PRS scope to be very easy to use. The turrets can be felt and heard with every click, making it easy to adjust blindly. Though it wouldn’t hurt my feelings if they were a touch sharper. Shooting back and forth from near to far, I had no problems focusing the reticle for sharp contrast on the target. The included throw-lever made it easy to swing between magnification settings.
Quality
The feel of this scope is robust, it feels well built. With its oversized turrets I would expect it to stand up to bumping into and getting smacked during use. As I moved from target to target while shooting, not once did I feel like I was looking through a cheap scope. It looked like the sharp clear images I am used to seeing, allowing me to see the wind moving snowflakes across the hundreds of yards to the targets. And picking out the details of distant landscapes
Durability
Turning the controls of this scope in the freezing temps of the high Rocky Mountains didn’t change much to its feel. The way this scope seems a little bit overbuilt and gives the impression it will last through tough use. Time will tell of course if that proves to be the case, I’ll continue to use it as designed to see how it lasts. If you’d like to hear about that, check back in the future as I’ll update this review as time goes by.
So far, the bouncing about in a scabbard on an ATV, or in a soft case in the bed of the truck haven’t seemed to phase the scope. Carried on a sling through snow and brush, dialing back and forth sweeping both power and corrections it hasn’t lost zero or focus. Which I’d consider the bare minimum for durability
Accuracy
I like to bolt down scopes to a sturdy mount, and see how they measure up against their actual travel. To do this, I put out a yardstick at 100 yards, and measure the travel of the reticle. I do this both against the yardstick, as well as the reticle measurement to see how close they measure up. This way I can confirm repeatability and actual travel vs. the indicated.
On paper you can also see this manifest doing a box test. DiscoveryOpt’s scope was more than close enough for most of the shooting I do. Making corrections and come-ups precise enough for first rounds hits time after time.
Pros and Cons
There are many things to like about this scope, but there are a few things I would count against it. These aren’t a huge deal depending on your shooting practices and budget, but they are things you should know before you buy it.
Cons
First off, this scope is pretty big. You can probably tell in my pictures that is is bulkier than most comparable scopes. I have many 56mm objective scopes, this one has the largest external diameter of all of them, many of them easily fit inside this one. And it’s not just the body of the scope, turning the turrets on this bad boy make you feel like a Soviet Akula submarine operator.
Ok, maybe I exaggerate a little, but they are the biggest I’ve seen. Additionally, as soon as I picked up the box containing this scope, I knew she was gonna be heavy. At 44-ounces it might be the heaviest 5-25X scope in my inventory.
But even with all that said, I must temper it with the price point. At print, the MSRP of this scope is $359.99. Which is $200 less than the comparable Arken I recently reviewed. And after shooting the Discovery Optics scope, I think the only reason I’d choose the Arken over this would be weight requirements. And these days people are throwing weights and extra things on their rifles anyways so it might not even be a problem. For some folks, the Chinese origin is reason enough to second guess one of these products. I’ll leave that up to your discretion.
Pros
Now let’s get to what I like about this scope; Optically it punches above its weight, a decade ago I would have expected looking through a Chinese scope under four-hundred dollars to look like a glass of tea. But even as my eyes begin to show their age, I think this scope looks pretty good. Sharp detail and good focus make placing precise hits and target identification great. The parallax adjustment is a bit touchy but fully functional, similar to the eye relief.
I mentioned the berthy turrets, but other than their size they are fantastic. Seeing the numbers up close is great with how big they are printed, and ten-MIL turrets are a must. And being able to easily and quickly slip the turrets to zero without any tools is a great feature. And the robust zero-stop is the coupe de gras for me.
The reticle inside is pretty close to what everybody is making these days. There is plenty of detail and subtensions for every need. I like that only the center 1MRAD is illuminated as well.
Value for your money might be the big thing here, the included extras and performance for such an entry level price would have blown the pants off of 2005 me. I can’t believe that as little as a decade or so ago, I paid more than this for scopes I would consider borderline trash today.
My Conclusion
My initial impression looking through these scopes was pretty positive, and after taking one out for some serious shooting my positivity remains. The concerns we all typically have with inexpensive scopes made in China seem to have been overcome these days. For at least this scope, I feel like the performance more than warrants its price. Giving judicious shooters a great value with all the features we like in our precision rifle scopes.
