XTR II Riflescope Reticles

XTR II riflescopes give you a variety of reticle choices, and

feature front, rear, or dual focal plane systems.

Front Focal Plane (FFP)

Front Focal Plane systems (sometimes referred to as

First Focal Plane systems) place the reticle in front of the

erector assembly or zoom mechanism. This allows the

reticle to change size as magnification is adjusted. In

FFP systems, when magnification is increased, the

reticle size grows; as magnification is lowered, the

reticle size shrinks. Because the reticle is changing with

magnification, the measurements of the reticle are

always correct and are proportional to whatever power

setting you may be on. This can be very useful in tactical

situations when reticles are used to determine size and

distance of a target, and when using the reticle for trajec-

tory compensation at multiple magnification settings.

Rear Focal Plane (RFP)

Rear Focal Plane systems (sometimes referred to as

Second Focal Plane systems) place the reticle to the rear

of the erector assembly or zoom mechanism. This is the

most common reticle system and is found in most

hunting optics. Because the reticle is behind the zoom

mechanism, the size of the reticle is constant and does

not change when magnification is adjusted. This will

make the reticle appear to consume more of the target

on low power; on high power, the reticle will appear to

consume less of the target, which is beneficial for long-

range, precision shooting.

Since the reticle size never changes on RFP systems, it is

important to understand that the reticle measurements

will only be correct on one specific power. For the XTR II

1x-5x riflescope, the measurements are correct at 5x power.
