Rated 5 out of 5 by from great glass,great retical,indistructable i have three vortex scopes along with nikon,leupold and bushnell but i am the most confident is vortex scopes. my pst 2.5-10 i have mounted on my savage arms msr 15 and i think it’s the perfect match. i have enuff scope to reach out to over 500 yds and hit a 4” gong but still can hit multiple targets under 25 yds in succession. the illuminated retical is nice for dusk or night but not bright enuff for use in full sun. turrets are crisp,positive and accurate. the 30mm tube truly comes in to play with light transmission,as it allows you to see well past dark or even in the dark on the right nigh coyote hunting. overall great product!

Rated 5 out of 5 by from EXCELLENCE. I have this scope mounted on my BCM 16" Stainless Steel RECCE. Shooting out to about 600 yards with 77gr is a breeze with this thing. Clarity, build, and finish is excellence. I own two other PST scopes as well, and am looking into a fourth. I always want to purchase a NightForce when I'm looking for new glass, but Vortex is just too good at the price point. I can't justify shelling out that kind of cash when Vortex optics get the job done just as well. I am a currently a recreational shooter, but did my time in the Army as an SDM, am have plenty of time behind lots of glass. Vortex has me sold.

Rated 5 out of 5 by from Great performance and price. I was searching for the right scope for my M1A. The performance of the scope is about prefect for my tired eyes. 2.5x is enough power for closer targets and the 10x is high enough to to reach out to 500 yards for my eyes. The illumination is high enough for me on mixed cloudy days and the glass is really clear. I weighed the benefits of the FFP vs the the extra light from a 44mm lens and chose this model. The warranty is top notch. I am very satisfied with my purchase and will buy Vortex again.
