Solid cost/benefit - Vortex Viper PST 4-16x50 FFP Rifle scope

I was in the market for a First Focal Plane (FFP) optic with solid quality and robust features that wasn't going to break the bank. I think I found it in the Vortex Viper. I am utilizing this scope with a .308 caliber rifle. I doubt that I'll shoot past 600m with this rifle; simply because there are limited places to do so where I am. Set-up was easy; and I mounted using a Vortex 30mm cantilever scope base with QD attachments. The first three rounds out of the bore with the new optic were 3.5 cm low at 50 yards. Made the adjustment and was zeroed at 50 and ready to start moving back. Three rounds to zero is pretty nice if you ask me; not to mention the three impacts were touching. The clicks on the turrets are tactile and appear to be accurate. In the process of zeroing, I was able to make various adjustments for various ranges; then using the data obtained return to those zeros and put accurate rounds on target without issue. I haven't shot at night with it yet; so, I won't comment on the illuminated reticle. However, I will mention that the EBR-1 reticle is sharp; and provides a good deal of functionality. The number and layout of the subtentions allow the user to gather relatively precise data when compared with a round or oblong mil-dot reticle. The ocular focus is smooth and I have not yet had any trouble with it coming out of adjustment. The magnification ring is a little stiffer than I'd like; but definitely not a deal breaker. Parallax adjustment is smooth and stays put once you've made the adjustment. There is clearer glass on the market; but I don't know that there's any clearer glass for this money or maybe even the next price point above. Combine all this with Vortex's warranty; and I think there are a lot of shooters, for which this optic makes sense.
