When you see the crystal clear image quality, feel the precision turret dialing system and experience the rugged dependability in the field, you’ll understand why people rarely end up with just one Viper riflescope. Whether you hunt the east coast or the west coast, or just need a reliably accurate riflescope ready to consistently punch tight groups at the range, the Viper is up to the task. The Precision-Glide Erector System uses premium components in the zoom lens mechanism to ensure smooth magnification changes under the harshest conditions. Surely something with the quality necessary to be this versatile would cost an arm and a leg, right? Not this time, the Viper pleasantly surprises with that "more than what you paid for" feeling.

Rated 5 out of 5 by from One of my favorite Vortex Scopes! I had always been a Leupold fan and used their scopes for competitive shooting for years but Vortex has changed all that! While I no longer compete, I do still love long range shooting and hunting. My custom Remington 22-250 "coyote" rifle wears a Vortex Viper 3.5-10x50 scope with Dead Hold BDC reticle and I could not be happier! The sharpness, clarity and precision of the Vortex scope rivals anything I have ever used. I was so impressed with it that I now also own Vortex binoculars and spotting scopes as well. My last trip to the range with this combo produced a 3/4" group at 200 yards and a 1 1/4" group at 300 yards. It just doesn't get much better than that!

Rated 5 out of 5 by from Great Scope I have used the Viper 3.5-10x50 scope for the last 5 years, it is on my main whitetail hunting rifle. I am very serious about my whitetail hunts and Vortex scopes are what I trust when I hit the woods. This Viper scope, even though it is not the top of their line, it performs flawlessly. Never fogs up, always a clear site window, and when it counts the light gathering that the 50mm objective provides is plenty to keep hunting until last light. I have been able to harvest some great animals with this scope. I liked this scope so much I have bought several other Vortex products and have been very pleased with each one.

Rated 5 out of 5 by from Broke In college, Still won't sell out I bought my scope while I was dead broke in college. I couldn't even afford mounts to put it on my .270 for another 6 months! I had a buddy offer me money for it but one look through it and i was never gonna sell it. Super clear gathers light exceptionally well and I am by no means a "marksmen" but i have no trouble with shooting out to 600 yards thanks to the BDC recital that eliminates all the guess work. This scope also was in a car wreck and still works like a champ! Even if it was damaged the vortex VIP warranty gives me peace of mind.

Rated 5 out of 5 by from Couldn't Be Happier! I bought a Viper PST for a long range build last year and was so pleased with it that when I needed a scope for a 300WSM I acquired there was no question it would be another Vortex! I chose the Viper 3.5-10x50 for this weapon to shoot out to 500 yards in real hunting situations and conditions. No disappointments here. Function, fit, finish and quality are up there with scopes costing twice as much. I was a Leupold guy before I discovered Vortex, now Vortex is all I will buy!

Rated 5 out of 5 by from These scopes and optics are amazing and tough I've owned 4 scopes from these guys and they have never let me down, i have this particular one on my 300wsm and i love it, clear picture perfect picture and i realy like the dead hold bdc radicals for long rang shots. I will always stand by vortex no matter what there products are tough and durable and thats exactly what us mountain hunters need. I own a pair of there binoculars and there range finder too and i have no complaints about those neither. There stuff rocks!!!

Rated 5 out of 5 by from Over all great scope. Bought this scope about 4 years ago. I have it mounted on a Savage 30-06. I have taken a moose, mule deer buck, and a black bear, all at different distances. I love the dead-hold BDC that it has. All my game were take with one shot.This scope is so clear and bright it does not matter what the conditions are. I am thinking of up grading my 2 daughters scopes to Vortex. It is an awesome all around scope with an awesome warranty. I highly recommend this product.

Rated 5 out of 5 by from Buy this brand and never look back! So ive owned and used nikon,Swarovski, bushnell, meopta, nightforce, and leupolds. While my scope at this price point on sale is not as nice as the nightforce its close enough that for the price difference ill never hesitate to save up and buy one of their higher priced models. This scope was a steal on sale and compares with much higher priced scopes from other brands. The clarity is really nice, and this 50mm gathers light like tinkerbell on steroids. As for customer service ive only asked a question via email about helping me recomend a strong scope for my 45/70 that I load hot. They answered emails back and forth the next day. So if that and all the other testimonials are an indication then they will be top notch like others have stated over and over. Buy a Vortex, and go hunt. Never worry again if your scope will fail you during a hunt.

Rated 5 out of 5 by from Great Scope - Very Clear Purchased a Viper 3.5 - 10 x50 BDC in early 2015 and replaced a major brand scope on a my Weatherby 25-06. During 2015 Missouri Deer Season my son (11 years) placed a perfect shot 200 yards on a doe. One shot one kill - dropped in her tracks. Great - Clear Scope I am so grad I replaced my (other) scope. Just purchased a new 4-12 x50 to replace a scope on my 257 Roberts. Good Job Guys keep up the good work.
