Second focal-plane, which is typically found in moderately powered hunting optics like the Diamondback 3.5-10x50, will allow for a very visible reticle at any magnification, but one that would require the user to be on what is known as the "subtension magnification", in this case 10x, for using any subtensions below, above, or to the sides of the center intersection as designed. In short, their values are only accurate at this subtension value, and in the case of this optic at 10x, they would be 1.5, 4.5, 7.5, and 11MOA as measured from the center on the vertical, and 2MOA each as measured from the center on the horizontal. Because these optics are typically utilized as hunting optics, and for ranges from 100 - 500 yards, we can typically assume that for shots at the longer ranges, higher magnification would be utilized, and there should be little worry about being off of that subtension magnification for accurate holdovers, and conversely, shorter distance shots would allow for demagnifying - but still requiring a highly visible reticle - which the second focal-plane offers.
For contrast, a first focal-plane reticle scales in-time with magnification change, keeping those subtension values accurate at any magnification - however - it will appear as if the reticle is growing and shrinking with magnification change. On a high-magnification optic - say 6-24x50 - this is often seen as advantageous, as it allows the user to utilize holdovers at any magnification at which he or she could see the reticle, and as is often the case, may find it beneficial to be at lower-than-maximum mag. A possible detractor to first focal-plane would be the limited visibility of the reticle at the bottom end of the magnification range, as it "shrinks" considerably.
The Diamondback scopes are produced in China.
The V-Plex variant is indeed! Avoid the BDC variant otherwise in the selection process.
If you have R/L on the 12-oclock position, and the U/D on the 3-oclock position, this should indeed be switched. If your turret orientation is 9-oclock and 12-oclock, the optic would otherwise be 90-degrees sideways.
The Vortex Diamondback 3.5-10x50mm 1in Tube Second Focal Plane Rifle Scope has Zero Reset Turrets.
Unfortunately, we do not carry a sunshade that is compatible with this Vortex Diamondback 3.5-10x50mm Rifle Scope.
On the Winchester XPR, a 1-piece picatinny rail, like the EGW 0-MOA, paired with a set of our Pro-Series 1" medium-height rings would be an ideal fit!

The Vortex Diamondback 3.5-10x50mm Rifle Scope will be able to handle the recoil of a Marlin chambered in 45-70. The Vortex Diamondback 3.5-10x50mm Rifle Scopes are factory tested under a force of 1000 G's 500 times to ensure that they can handle heavy recoil.
To mount the Vortex Diamondback 3.5-10x50mm Rifle Scope to a rifle chambered in 204 Ruger would depend on the model rifle you have and the bases you are using. Here is a guide that can help you determine the rings you need:
