Great scope but my loss

I love this scope on my Tikka UPR. Unfortunately I bought it last year not realizing it didn't have the RZR system. On clearance I guess. I can't afford another scope in this price range so it will do I guess. Though it seems it's no longer in production. Either way excellent glass and precise adjustments are spot on.

Viper PST GEN II

Good scope for its magnification. I used this scope on variety of different platforms, and it performed well. I did end up wanting to upgrade glass to something higher end. But I had no issues with this scope

Amazing build quality and clarity

The vortex pst gen 2 is probably my favourite scope in my entire lineup. It blows away other similarly-priced scopes with its exceptional glass quality, field of view, and crisp reticle. The turrets on the Viper are super tactile as well. I will be purchasing more vortex scopes; their entire lineup is hard to beat. It seems they have a scope for every application. I would love to have the chance to test out their other optics!!

Mounted scope to mosberg patriot 300 winmag

Box got to me almost the very next day and I mounted it that very weekend. Scope has many amazing features a zero stop , parallax adjustment among others, zeroed it at 100 yards in 8 rounds im shooting a nickel size group. I plan to really stretch its legs big thanks to Vortex for such an amazing piece of gear and thank you expert voice for this opportuVortex. Have another scope a strike eagle on my my ar and have the same 5 star performance. 10/10 if you want to shoot a flea off a gnats rear buy vortex.

Fantastic scope for the mid

Fantastic scope for the mid range price. Offers plenty of magnification for long range shots. Not extremely heavy. It is fairly large but it feels necessary for the solid glass quality and level of magnification. If your an experienced shooter and looking to extend your shots into the longer ranges this is a phenomenal option.

PST Gen II 5-25x50

Was looking for a 30 mm tube, 50mm Bell, illuminated reticle, second focal plane with a wide range of zoom for hunting but still under Razor or VX6 price range as it is not my daily hunter and this scope was the perfect fit for AR10. Turrets are crisp, vortex glass has amazing clarity, zero "fish bowl" on the edges of the field of view. Wish they included a throw lever but for half the price of a VX6HD or Razor it is a fantastic optic.

I have used this scope for target shooting and hunting. Just killed a bull elk with it at 400 yards. I have used this optic on my 224 Valkryie, 6.5 PRC, and 7 SAUM with flawless results.

This was my first Vortex

This was my first Vortex purchase. I mounted it to a Ruger Precision Rifle and could not be happier. The glass is as clear as my more expensive but lesser powered Zeiss scopes. I also love the reticle. It is a little busy but a snap once I got used to it. Am going to order another for a Remington build I am working on.

Fantastic Optic

Great magnification range. Bright images, outstanding color correctness, excellent fine detail, outstanding tracking. Dead on tracking on "Box Test". Turrets have nice tactile feel. Parallax adjustment range is very nice, especially at closer ranges. I own 4 of these scopes, using them on CZ 457 and VuDoo V22 precision bolt action .22 LR. I have purchased these scopes for the last 4 years. I shoot approximately 10,000 rounds rimfire ammo per year. Never a problem. Never a complaint. Friends I shoot with always envy these scopes.
