You’re comparing two very different designs between the ATACR 1-8 and the Razor 1-6. The ATACR is FFP, vs the Razor SFP. Buy virtue of how they are made, the Razor is going to have a “bigger, more forgiving eye box.” It has to do with where the reticle is placed in the body of the scope. The SFP will give you that huge, “disappearing” edges thing that the Razor is famous for. It’s good glass. For what it is. The difference is, the ATACR has an incredible reticle that has true sub tensions at every power level. The Razor only is true at 6X. Most people, myself included, will tell you SFP is great UP TO 1-6. Most want a FFP after that.
I ran the Razor for several years when it was the shit hot LPV. Now I’m running the FFP NX8 and the ATACR 1-8. I sold my Razor when my ATACR arrived. The NF is in a different catagory. That being said, the Razor can be had for about $1000 street price. The ATACR 1-8 is still a solid $2200. Is the ATACR 2X the scope? Only you can decide that. I use my scopes for a living, so for me, it’s worth it.
