Last year, Discovery impressed me with the ED-PRS Gen2 5-25×56 scope with its high-quality glass, features, and street price under $500. They told me they were working on a 6-36x version but had delayed production until they were satisfied with the results. The wait is finally over with the XED 6-36×56 with a street price of just under $700.
This scope is share many of the features of the new ED-PRS Gen2 MOA like its new throw lever design and its tool-free turret screw tops. The XED is slightly longer and heavier overall with a noticeably wider parallax dial than the ED-PRS. The biggest change is the XED’s 35mm tube which allows a wider range of adjustments.
The XED utilizes Japanese ED glass for excellent optical clarity and brightness while minimizing chromatic aberration. Most high power scopes have tight eyeboxes, the XED is unforgiving at 36x. Tight eyebox aside, for those that require a bit more magnification than the ED-PRS 5-25x, the XED is tough to beat.
It’s hard to believe, but you can improve your long range accuracy for less than $20 by simply attaching a spirit bubble level to your scope. Discovery Optics makes such an accessory. It’s a spirit level mounted in a metal ring which you can clamp onto your scope tube to you can read the angle and levelness of your scope and rifle setup.
If your scope is not 100% directly above your rifle bore, which can happen as you press your cheek to your stock or simply adjusting your shooting position, or when setting up a hasty shooting position, this can create a slight canted angle either to the right or left of center. This will in turn can make your shot land ever so slightly to the right or left of your aim point. By assuring your scope is level to your bore with a spirit level, you can avoid this simple mistake.
This scope level is made of aircraft grade 6061 aluminum alloy with an easy-to-read bubble bead in the spirit tube. It comes with two ring adapters allowing the bubble level to be mounted on either 1″ (25.4mm), 30mm, or 34mm scope tubes. It is probably the best $20 you’ll spend on your scope set up.
It’s deja vua all over again. It felt like I had just reviewed the ED-PRS Gen2 5-25×56 about a year ago. This scope had some slight changes to the turret and improvements to the clarity and sharpness of the glass. Discovery asked me to review a new ED-PRS Gen2 5-25×56 in MOA, but this scope has even more changes than just the reticle.
The size and weight of this scope remain the same at about 4 lbs and over 16″ long; over 19″ with the sun shade attached. Discovery changed the turrets which no longer have silvered screw-in tops. The new version has black tops that have indents so that they can be unscrewed with your fingers allowing the turrets to be zero-set without tools. The previous Gen 2 had a shorter windage turret held in with 3 set screws. Discovery changed the windage turret which now has the same tool-less turret as the elevation.
Discovery also changed the design of the throw lever. Instead of a screw-in post, the new throw lever has a more robust flattened shape with a broader base that connects to the magnification ring. The lever is now held in place with two torx screws.
Discovery scopes come with a ludicrous amount of accessories. But with this and future ED-PRS scopes, they’ve removed the scope rings. Too many customers complained about the high-hight scope rings they included previously and asked for exchanges or returns, so Discovery chose to remove the free rings from the package. This is why we can’t have nice things.
The new Gen 2 retains and possibly improves the quality of the Japanese ED glass. This scope appears slightly sharper and clearer than my old Gen 2 MIL version. Unfortunately, it still has the same unforgiving eyebox. And another important feature that hasn’t changed: the price. This new scope is still about $350, which keeps the ED-PRS the best value in its class.
Last October, I competed in an NRA Falling Plates match at the Coyote Point Rifle and Pistol Club. I had a really good run through the match until the last rounds when I missed a string of plates. For most of that match, I was able to use my new ED-AR LPVO at 1x due to its clarity. But in the last stage, I increased the magnification to 3x and wasn’t used to the reticle change on this first focal plane (FFP) optic and that made me panic a bit and rush through my round. I choked and ended up blowing my tie for the lead.
Three months later, I’ve had more experience with this scope. I took the same rifle and scope to the January 18, 2025 match to see if I could redeem myself. This time there were 20 contestants. This year, we added a 5th stage to the matches, ending at a distance of 50 yards, which makes a magnified optic almost necessary to aim at 6″ plates.
We start from a distance of 30 yards with a 10-second time limit to shoot down 6 steel plates, limited to 6 rounds of ammo. Each shooter gets 2 attempts per stage. After all competitors have shot, the stage position moves back 5 yards and the time limit is increased by 1 second.
I did well through the first 3 rounds only missing 1 plate out of 18. But moving out to 40 yards, the plates were harder for everybody to hit. I moved my magnification up from 1x to 2x and then to 3x. I still prefer a SFP for an LPVO in action shooting. But unlike my previous attempt, I had a few months of range practice getting used to this scope.
I honestly did not think I did that well. So I was frankly surprised that I came in 4th place but only 3 points behind the 1st place shooter. If I’d only slowed down on hit 3 or 4 more plates, I could have won it. Maybe next time.
Discovery Optics is known for making high-quality shooting optics for ridiculously affordable prices. I’ve reviewed a number of their scopes over the last two years. Discovery Optics attended SHOT show for the very first time this year. At their booth, they showed off a brand new version of their flagship ED-PRS scope.
The ED-PRS is a Chinese-made scope that uses Japanese ED glass and is designed for PRS shooters. Almost all of Discovery Optics’ tactical and competition scopes are built with MIL reticles and turrets. But many American hunters and long-range shooters, prefer MOA measurements for their finer level of adjustment. Discovery listened to user feedback have released the 5-25×56 ED-PRS in MOA.
At their booth, I got my first-hand look at the new ED-PRS MOA and met fellow YouTube reviewer GunTotinMN who was working for Discovery as their presenter for SHOT 2025.
Discovery Optics is known for making high-quality optics for ridiculously affordable prices. But what I discovered at their SHOT Show 2025 booth was something even more surprising than a new scope, it was a prototype of a budget thermal scanner.
It was closer to a pre-production model than a rough prototype. The body was milled aluminium and the controls and displays were well thought out. The unit was about the size of an EOTech holographic sight. It has a QD Picatinny base that mates with an included handle.
Its primary use is as a handheld thermal scanning camera to look for living creatures such as game or search-and-rescue. Because of its base, it could be mounted onto a rifle rail and has been recoil-rated to .308 and higher. There was a high-resolution and a cheaper low-resolution version.
They say “Less is More” that could certainly be said of the ED-PRS GenII 4-20×52 scope. Earlier this year, I reviewed Discovery Optics new GenII revision of their ED-PRS 5-25×56 scope. The GenII EP-PRS boasted improved optical clarity by using Japanese ED glass. So, why would they make a 20x scope when they already offered a 25x? And why would you want to buy one?
The 20x version appears nearly identical to the 25x. In terms of performance, the 20x has a 4x magnification factor which means in theory it should provide slightly a sharper and brighter image when set to the same power numbers as the 25x. In my testing, the differences were too subtle for me to see. But what I could clearly see is that the 20x is slightly shorter, slightly lighter, and slightly cheaper than the 25x.
Moreover, most hunters and target shooters don’t typically shoot a 5-25x scope at its maximum 25x; preferring a setting of about 12x or 16x to improve clarity and brightness. A 20x scope is able to be used at 12-18x. Let me again remind you that the 20x is slightly shorter, slightly lighter, and slightly cheaper than the 25x. It all starts to make more practical sense.
The Discovery LHD 8-32×56 is a surprisingly low priced 32x scope. Unlike previous long-range scopes from Discovery, my sample model did not come with scope rings. This may be a new direction from Discovery, hoping to move away from the perception that they are a “budget brand” that come with plethora of accessories. Leupold, Athlon, Vortex, Burris; none of the big name scope brands come with rings or mounts for their long range scopes.
The LHD appears made for long range Benchrest style shooting at over 2lbs (35.6 oz). It has tall, non-locking turrets which provide loud and tactile positive clicks. The elevation turret has a cog-and-tooth style zero stop which is solid and repeatable. In my range testing, the turret tracked precisely to my MIL grid target at 100yrds.
The magnification ring was stiff but thankfully it comes with metal throw lever, which it needs. The LHD uses relatively sharp HD glass which exhibits typical amounts of chromatic aberration (CA). This CA reduces contrast and sharpness at its highest magnification, which takes away from what on paper should be an impressive 32x.
The LHD has a FFP Christmas Tree reticle that is mostly skeletonized and thin to optimize visibility at higher magnification and longer distance objects. The illumination lights up the center 1/4 of of the cross hairs and is low-light/twilight bright. Helpful for black bullseye targets or shooting in early dawn or dusk but not “daylight bright”.
A disappointment in this scope for me is its tight eyebox. Most high magnification factor scopes suffer from this. Even at it widest setting of 8x the scope has an unforgiving eyebox that only gets tighter that higher you crank the magnification. For a Benchrest or F/class shooter this isn’t as much of an issue but would be very frustrating to a hunter and competing in PRS/NRL matches.
Overall performance and build quality reminds me a lot of the Arken SH4. The LHD offers similar performance at higher magnification for just under $250. While this scope won’t compete with premium +30x scopes like the Athlon Ares or Vortex Golden Eagle, the LHD outperforms anything close to its price class.
If you own a pair of scope rings or really any firearms accessory that’s made of metal, chances are that metal is aluminum. And if you look at the marketing description it may describe it as “Aircraft grade” aluminum or “Aluminum Aloy” which means that chances are that type of aluminum is 6061.
But there is also 7075 aluminum which was secretly invented in Japan before WWII and used in the famous Mitsubishi A6m “Zero” fighter. This aluminum is technically lighter and harder than 6061. But also harder to mill and work with, which makes it more expensive than 6061.
Discovery optics new line of scope rings and mounts are surprisingly well designed and constructed, with features like lightening cuts and recoil lugs. Moreover they all feature clearly printed informative labels with useful information like the height and diameter or the rings, the amount of torque to apply to the star Torq screws, and the sequence to tighten them down.
The 6061 “lightweight” cantilever offset mount features an index pin to more precisely align the top and bottom halves of the rings together and provide reinforcement against recoil sheering sheering forces on the screws. As the name implies their 20MOA Heavy Duty mount has a 20MOA cant built into the base for Extreme Long Range shooters and features “Pre-Lapped” rings that are polished down to the bare metal providing the mirror smooth contact surface with your scope tube. It also offers 6 screws per scope ring which offers more clamping power if you’re mounting a heavy scope on a big bore (ie. 50BMG) or magnum cartridge rifle.
If you don’t need the 20MOA for pushing out to Extreme Long Rang shooting, you probably don’t want it because that also means you’ll need to compensate by adjusting your scope 20MOA to counteract that ballistic drop of the mount for “normal” range setups.
Both the 6061 and the 7075 rings also feature this pre-lapped treatment. In fact, I’m a bit hard pressed to find a use case for the 6061 rings over the 7075 rings. Certainly the 6061 rings are lighter and 40% cheaper than the 7075 rings but both are under $100 and therefore so affordable as to make the difference in price negligible.
In general you should choose scope rings for the most versatility in scope setups on bolt action and semi-automatic rifles. Discovery Scope mounts will only fit on Picatinny 1913 rails due to their triple recoil lug bases. But if you’re mounting a scope on an AR or a rifle with limited rail space, you may need a mount to provide enough forward offset to push your scope eyepiece far enough forward to provide you with sufficient eye relief to use the scope safely and effectively.
No matter which you choose: scope rings or an offset scope mount, Discovery’s offers exceptional value and by all appearance, exceptional engineering and construction. In all but the most extreme conditions, either 7075 or 6061 should provide you with a strong enough mounting system for your scope.
I recently reviewed the ED-AR LPVO from Discovery Optics. I even performed a drop test on it and it held zero (though it did shift after dropping, it held that shifted zero). This weekend I had an opportunity to put it through a performance test by using it as my optic in a Falling Plates Match at the Coyote Point Rifle and Pistol Club (CPRPC).
I zero’d out the scope and it performed well. Despite the ED-AR’s middling illumination brightness, it was more then sufficient in helping see a visible aimpoint against a white metal plate and the dark grey of the backstop. Except for one ammo malfunction on my last shot in the first round, I had perfect scores all the way through.
But it all fell apart on my final round. I’d been running the scope at 1x through the first 3 rounds of the match from 30yrds, 35yrds, and 40yrds. But for the last round at 45yrds, I decided to change my magnification from 1x to 3x matching the size of the reticle round to the size of the plate at this distance. I thought that would make it easier to hit the targets. Instead it did the opposite: it made me slower and less steady.
What I failed to realize is that when I had been practicing before the match, I had the scope at 1x. I had gotten used to aiming with the reticle at that size. Moreover each round during the match had given me extra practice and experience shooting with the scope set at 1x. When I switched it to 3x, I didn’t have any practice at it. I was fighting against my muscle memory and the increased magnification made my aim more “jumpy”.
I flubbed my first string only knocking down 2 out of the 6 plates. My second string was better but I only managed 4 out of the 6. Lesson learned: don’t introduce new variables into your optic during a match, without practicing it before hand.
Instead of coming in first (had I against scored a perfect 6 as my previous two rounds). I came in 4th. If it ain’t broke, don’t fix it.
