Re: Comparable to Bushnell HDMR 3.5x21x50?
You don't say which reticle you want.
If you want the reticle choices and the quality you need to spend more. For the same reticle choices I think you'd have to go with a custom USO, they are going to be the only ones offering "anything you want" type service with a custom build.
If you are looking at comparable scopes off of the shelf, the SS 5-25 ($1.5K), the Vortex Razor ($2K), a USO ($2.5)probably the NF F1 ($2.3K). You can get a NF NSX but it's not a FFP scope.
That pretty much covers the bases. Top of the line you can go to Schmidt and Benders or Hensholdt but that's north of $3K.
