Rated 5 out of 5 by from Perfect fit! For me specifically this scope is a perfect do it all scope. I hunt, occasionally long range shoot, and use as a potential recon/defense set up. I run a Remington 700 .308 and it serves as my only long range gun. I hunt mule deer in Wyoming, shoot at a long range course, and use for any other shooting opportunities among other things. The score is clear and rugged has never lost zero despite some pretty nasty drops. I have used 3 different vortex vipers on my gun and would recommend them to anyone looking for similar functions out of their glass. I don’t feel I need a razor because of budget and the fact it’s not a duty gun. 5 out of 5 with a great price point!

Rated 5 out of 5 by from I now have 2 scopes Great for low recoil like .204R, .22-.250, .243 and such because short eye relief. Would recommend extension rings or bases for mounting on long action rifles and mounting this scope on a long action Ruger M77 would involve 30mm extension front ring. Like the optics - bright clear at max power with sharp defined edges of field. Adjustments are easy to make without tools - don't need Allen wrenches for tiny Allen screws. Just pull out turn and push back. I have them set for 70 grain Berger VLD .22-.250 and 87 Hornady VMax zeroed at 200 and 2nd bar down hits at 300 for both. I can look through these scopes for hours without problems.

Rated 5 out of 5 by from AR-10 I use this riflescope to shoot long range on my ar-10, it is amazing at what it does. We get back 500-700 yards and dial the elevation in and start plinking at the steel. This scope is really clear and really holds its zero, at the price it's unbeatable. I've had this original one for about two years and have since bought three more of these and a rangefinder that also work great. I did have an issue with one of them with the elevation knob coming off and had it sent and returned from vortex customer service within a week, and has worked great since. Thank you Vortex for making great scopes affordable!

Rated 5 out of 5 by from More then expected When I picked up the scope I was looking for a good mid range scope. After a trip to Alaska to hunt caribou at long range with my son I found I had as good a scope as you can get. It rained almost none stop for the 7 days we hunted with an avg. temp of 40 degrees F. Not one problem and was dead on when I got my shot. My son was using another brand scope that cost 5 times what I paid. Yes, he paid over $1500 for his scope just to have it fog up when we got above the 9000 ft level. He ended up mounting my viper and finishing his hunt. When we got back to Utah he went out and bought his own Viper and I just as pleased with it as I am.

Rated 5 out of 5 by from Great News While hunting coyotes, I jumped a frozen stream and fell on my back, directly on my scope. My scope was so badly bent, I was through hunting for the day. I sent my scope in to Vortex. By return mail I received the following. Mr Butler. We are sorry that your scope is so badly bent that it is beyond repair. Please find enclosed a new scope as per our guarentee. Great news. great scope, great guarentee and great company.

Rated 5 out of 5 by from Love it so far! I picked up my viper HS 4-16x44 bdc for a steal. I purchased it to set on my T/C Venture 7mm Rem mag.... This scope with that gun = budget friendly DEADLY accurate shooting. I bought it for an elk hunt coming up this fall, haven't gotten to test it out on a real hunt yet. However, on the range it's great...seemed to track well while sighting it in. I tested the hashmarks out to 450 yds using a ballistics calculator and they are exactly where they are supposed to be. Very happy with this scope. I almost wish I had gotten the ones with the external turrets, but the capped ones work great too...and the instant zero reset is a very convenient feature.

Rated 5 out of 5 by from Awesome scope and so much more than expected So my brother has this scope on his Remington 700 and brought it to the range. Of course I had just bought the sweetest rifle I could get my hands on with a scope already on it that had every thing you think you would need and even more. Well here is the thing I looked through his scope and everything was clearer and sharper with way more definition. Ok his viper is better to see through but he didn't have the magnification I did so could beat him there. Well let me tell you this scope has way more than enough for out to 500 and probably even further and has all the necessities you would even need and way easier to use then mine. So hopefully pick one up next week.

Rated 5 out of 5 by from Excellent Low-light Quality I bought this scope to put on my Tikka T3 .270 Win. Mounted it with DNZ rings. It was super easy to sight in this scope. Did the normal routine, and within a few rounds I had this scope dialed in. The reticle is VERY easy to see in low light conditions, something that was very important to me for hunting early and late. Windage and Elevation dials feel very durable, but are easy to rotate, but stay put. Power adjustment is quite stiff, but I'd imagine it will break in after some use. Glass is clear and bright. I also got a great price on it too, which makes the value even better.

Rated 5 out of 5 by from Serious performance and great value. I bought this Viper 6.5-20x50 Dead Hold BDC to put on a Steyr Pro Hunter Varmint in 223 Rem and was immediately impressed with the clarity. After a few shots sighting it in I was breaking clays at 330yds. The Dead Hold BDC reticle made it easy and my brother, who has little shooting experience, was able to do the same. It's light transmission when shooting rabbits and hares over a spotlight was second to none. It was noticably better than my mate's Bushnell Elite which cost $400 more. I'm already considering which Vortex scope to get to replace a Leupold scope on another rifle I own as the Leupold does not suit.

Rated 5 out of 5 by from Best bang for the buck I initially purchased this optic for long range use, switched it over to my hunting rifle after discovering the Razor lineup. I purchased this for the father/brother in law's rifles as well. we all have taken deer with them in MO. lightweight, plenty of power and clear to see for early morning/late evening hunts. Tracks perfect. price point is probably the most notable feature vs the other companies. lots of features included that most don't include for the price. Ease of zeroing, reticle options, 20X power, 30mm main tube, mag lever (needed when wearing gloves), capped turrets, clear glass, tracks as it should in a quality glass.

Rated 5 out of 5 by from First higher end scope. I bought this scope from midway mounted it to a 300 win mag savage 116, have it on a 20 moa picatinny rail with the vortex rings. Eye relief is great on this scope until you get to x16 then it's a little finicky but still far better than my previous nikons. Love the turrets easy to adjust nice obvious clicks. I also added the vortex flip up lens caps to protect the investment and they ate or a lot higher quality than others I have owned also. This scope has easily gotten me out to 700 yards and I have a feeling I'll be able to hit that 1000 finally too. Glass is clear and bright, overall a great hunting scope. I truly belive vortex has got a lifelong customer here if they keep producing and backing up a product like this.

Rated 5 out of 5 by from Great Value I purchased this for my new X-Bolt in .308 to shoot 500yrds and less. I was pleasantly surprised at the clarity and brightness of this scope for the price point. I am also blown away by the warranty Vortex offers and support. I did have questions on the BDC reticle and when I called they answered promptly and provided the information I needed on hand. My experience was fantastic, they are my first choice for all of my optics moving forward.

Rated 5 out of 5 by from Coyotes set aside differences to protest of Vortex Optics Picked one of these up about three years back for a 700/308. Ended up so happy with the first I grabbed two more (700/223, m77/7mm), and have been equally pleased. I frequently dial up shots and consistently these scopes return to zero. The elevation turret came loose on the 308*. Contacted vortex and within 3 weeks the scope was back on the rifle. This little guy plopped down on his haunches at 500 yards. Dialed up the shot and the 308 anchored him with a brisket hit. *stuff happens, it's how stuff is dealt with after it happens that matters.

Rated 4 out of 5 by from Target and Hunting I put this scope on my 6.5 Grendel build a two years ago. I think its one of the best values in scopes. It provides plenty of adjustment for long range target shooting and isn't too big to take in the deer woods. The adjustments are accurate and the scope is clear down to the last bit of light. While I do take this rig deer hunting I will say for my eyes the crosshairs are a bit thin when hunting anywhere but fields. My eyes lose them from time to time in the woods. That's the tradeoff on having a reticle that's fine enough to target shooting.

Rated 4 out of 5 by from What I expected I’ve been using this optic for a little over two years now. I have the mildot reticle, mounted to a 20” AR in 5.56 that I mainly use for coyote hunting and distance shooting. The glass clarity is solid for the price point. The light transmission is decent in low light, enough so that I can just make out a coyote at 300 yds at night with a 1k lumen light. (The glass is clearer to the eye than shown in the photo, 12X20 plate at 500yds). The turrets are covered which isn’t ideal but they work just fine. The easy reset to zero I think should be set with a screw as one can accidentally pull up on the cap while making an adjustment and lose zero. Otherwise I have had no problems with the scope holding zero. It’s definitely a heavy optic so it’s best suited for a bench rifle. The zoom is more than enough for the capabilities of 5.56 (I’ve pushed it to 600 yds so far). Overall a solid optic for the price point.

Rated 2 out of 5 by from Nicely built, clear glass, but fatal flaw I picked this scope out to purchase after a lot of research. It is nicer than my previous Primary Arms 4-14x FFP scope as far as glass clarity and crispness in the elevation and windage dials, and the mildot reticle is sharp. The big issue: the reticle is mildot but the dials are MOA so in order to take advantage of the mildot you have to do conversions to and from the turrets. This is ridiculous. Mils for mildots and MOA for MOA reticles. Had I known this before I bought I would have selected another brand. I use mildot reticles with the Mildot Master computer and now have to add converting back and forth from MOA to mils and vis versa in normal use! I cannot say I'm a fan of both turrets being covered either. That might work OK with various types of Christmas Tree reticles but for a simple mildot or MOA reticle. These will require dialing.

Rated 5 out of 5 by from Performance I bought this scope a couple months back for my ruger precision rifle in 6.5 creedmore and it has done nothing but amaze me holding dime size groups at 200yards but will be reaching out way further in the next month or two!

Rated 5 out of 5 by from This scope is a Rockstar! I have been a Nikon scope guy my whole life. I had heard some rave reviews about vortex and their killer warranty so I decided to give them a try. What a great decision that was. This scope is crystal clear, even when fully zoomed in. The fast focus turret on the side makes focusing quick and easy. The anti fog is stellar and it holds a rock solid zero! Making adjustments were quick and predictable which had me sighted in and shooting groups I could cover with a quarter in only a few shots! Do yourself a favor! Get a Vortex.

Rated 5 out of 5 by from Great All Arounder I was given this optic as a gift that I initially install on a Ruger Hawkeye in 25-06, but it now resides on an Aero Precision .224 Valkyrie. This is the kind of scope that will work well on just about anything you put it on. Mine has the mil-dot reticle which makes it super useful for hold overs. The turrets have very nice accurate clicks and are super easy to reset. I really like the raised magnification marks especially since this is a sfp scope, the raised marks means you dont have to get out of position to make sure you're on the correct magnification! Glass is super clear and build quality is superb everywhere.

Rated 5 out of 5 by from Great scope for price I have had this scope for 2 years now and used it mounted on a 7-08 on more abusive and rugged hunts than the average. This scope has stood the test of climbing vertical slopes, being dropped down avalanche shoots, becoming fully encased in ice, and what always seems to be a scopes worst enemy, bouncing around in an atv. The scope has always remained true and kept its zero. There is no better scope for this price. I am looking to upgrade due to low light conditions and the clarity of this glass not cutting it for me personally. But again that desire is out of this price bracket. Great scope would highly recommend!

Rated 5 out of 5 by from Great scope. cant be beat for the money. I have two of these. one on a 22-250 and the other on a 25-06 (my two predator rifles). I have no complaints. they hold zero, they are durable, clear, and the dead hold BDC works great. I also like that the reticle is very light. some reticles have lines so heavy they block out small targets. I like that the turrets are capped, protected for normal use but you have the ability to dial in a shot if the situation allows. I haven't done a lot of doping for long shots with them but when I have they have both returned to zero every time. for the money they cant be beat.

Rated 5 out of 5 by from Excellent value! I bought one of these about six months ago and mounted it on a Savage FCP-SR .308 WIN rifle. I have shot in a couple of local precision rifle type matches with it and have been very happy with it. It has held its zero perfectly and the glass is very clear! The Mil-Dot reticle is why I chose this scope and it has not disappointed me, I only wish there was a First Focal Plane option. This is an excellent optic at its price point!

Rated 5 out of 5 by from Great Scopes Hi, I mounted my VIPER 6.5-20X50 PA RIFLESCOPE with the mil dot reticle on a custom A-10 Armalite Rifle. Always the Brite and clear views even in low light situations. The scope stands tall and easily holds up to the recoil of the 7.62, it stays on target always. So far I've been able to shoot a one inch group at 200 Yards. Hopefully I'll get better with more practive I Allowed ex Marine Sergent to shoot it he stated that the optics were on par with scopes costing lots more money. He further stated that he would like to set-up his next gun exactly like it. Not a bad compliment from a Iraq veteran with a Purple Heart & Bronze Star with valor. EMC SW Ret. William R. Galliher

Rated 5 out of 5 by from Look no further! Two years ago I needed a scope for my Remington .270 and with only a month before the deer hunt. A salesman at a local sporting goods store introduced me to this scope and he seemed very confident with it, so I decided to give it a try. I had it dialed in and felt very comfortable because of its accuracy in only a short visit to the range. I was able to harvest a great mule deer with it opening morning with one shot. Needless to say.. I have replaced my other name brand optics with Vortex and have had no regrets in doing so. This is a great scope and I am proud to represent it on the mountain and at the range!

Rated 4 out of 5 by from good value I have 2, 6.5-20X50's, both on light recoil .204R & .22-.250 - optics sort of approach Leupold 6.5-20X50 30mm but not quite but cost about 1/2. Have subjected both scopes to heavy use with no problems. Eye relief is quite short and ring mounting surface is limited making these scopes more suitable for short action rifles

Rated 5 out of 5 by from Worth the wait!!! This is my second Viper PA BDC. I purchased the Viper 6.5-20x50 PA BDC for my 700 Classic in .300 Wby Mag. I also have the 4-12x40 on a 700 ADL in .270 Win. both with DNZ Game Reaper mounts. I ordered this scope in January and it was on backorder. I finally received my scope 3 months later and it was well worth the wait. Mounting, boresighting, and zeroing were a breeze. My trip to the range for sight-in was a quick 6 rounds. Great clarity, beautiful sight picture. I have no doubt that this scope will serve me well as I prepare for an upcoming elk hunt. Thank you Vortex for another fine product!!!

Rated 4 out of 5 by from Good purchase great price I bought this for my 243 shooting varmits at the 5 to 600 yd distance. Good clear magnification at this range. Looses some clarity at lower light levels but overall a good solid scope for a great price.

Rated 5 out of 5 by from Great Low Light Clarity Bought this scope to glass out my 300WM for the 2017 hunting season. Like every other vortex scope I own, it performed perfectly but what set this scope apart from other brands is its ability to provide a clear picture during low light conditions. I was so pleased by its performance, I just purchased another one for my 6.5 creedmoor.

Rated 5 out of 5 by from Best scope in this price range I did my homework when it came to purchasing a nice scope for my tikka .270 hunting rifle, I landed with this cortex viper 6.5-20 BDC, and I am Suler happy with it. For the money you can not beat it. Period. I like pretty much everything about this scope, the only cons I would give it would be that it's maybe just a fraction to heavy(which is fine in the case of my rifle) and the clarity at full zoom isn't as good as some super high dollar scopes, but still much better then anything in this Price range, I would absolutely recommend this scope to anyone on the hunt for a nice set of eyes.

Rated 4 out of 5 by from Great scope lack of eye relief I have this in my browning AB3 300 win mag for a couple of months now together with a viper scope ring, like my other vortex scopes this scope is very clear, crispt image even at full magnification and it tracks very well, though the down side is the eye relief, this scope is a entry level for high powered rifle and its pretty scary to have the eyes pretty close to the scope. But all in all very good scope.
