Some background: My coach is an old school shooter and likes his scopes with a small dot and fine crosshair reticles with insane magnification levels and 1/8 MOA clicks. After a year of shooting with me and seeing the things I'm able to do with a scaled reticle and how easy it looks and how good the glass I use is for the price he decided to make the jump and get an FFP MIL/MIL optic. In prepping for a long range precision match a couple months ago we found out his Nikon scope was busted and wouldn't dial any windage and he was out of elevation for hitting the 900m target. Fast forward to last week and he'd ordered a new Vortex Viper PST FFP 6-24x with EBR-1 reticle. Now this is on a 6.5mm BR metallic silhouette race gun. The thing is meant exactly for standing up and doing it at long range... the hard way. Using it for PRS style work was actually really successful since it's nasty accurate and low recoiling but the busted fine hair and small dot Nikon scope wasn't helping. This is sure to help his scores in PRS type matches. How it'll do long term in Silhouette has a lot to do with how long it takes him to become friends with his new scope. Anyway, as soon as it arrived he ran over to my place and I dropped a set of my 30mm Burris Signature Series rings on the scope with 20MOA of cant dialed with the eccentric inserts. We got it mounted and took to bore sighting at yesterdays match. The scope was within 2MRAD of dead nuts right there. Looks like they're made for a 20MOA mount. There's a lot of stuff going on in the EBR-1 reticle compared to his old target dot (but nothing near as much as in the EBR-2 tree style) and in silhouette there's a saying that every change in weapon/scope/spotter takes a year to overcome. Apart from the newness and differentness for my coach, we just slapped a tactical oriented scope on a custom made race gun built specifically for metallic silhouette and not so much for tactical. Well, it looks like this change didn't take so long for him to deal with. He picked up 3 targets more than he has in the past 4 matches with that rifle with the new scope and we'd only just zero'd it right before the match started. In the meantime I had some time behind the newest Viper PST and I gotta say that while there are several design/feature elements that I really don't dig on, the overall quality and especially the glass was extremely nice. Bright and clear as hell all the way to the edges even on 24x and while there is a preference for greens and browns in the color rendition it's everything I'd expect from about 800 bucks. Yeah, yeah. I can hear you grumbling. Asking yourself, "What the hell is it that he doesn't like?" Ok, here's a list: 5MRAD per turn turrets. Pinch screw turret cap attachment system. Visible gap between objective bell and sunshade when so equipped. Mechanical illumination. Illumination rheostat location can cause issues with bolt knob interference on LH guns. Non-intuitive direction of rotation for side parallax (personal peeve). Side parallax knob is too low profile and not knurled. Turret labeling and the little window thing on the elevation turret is really busy and can be hard to read quickly. As you can see. Not a single one of my complaints has anything to do with the ability of the scope to perform reliably or accurately or even exactly as you'd expect. They're as close to first world problems as you can get but they do affect the speed and ease of use which are important criteria to me.
