WHAT IS THE LTT REAR SIGHT FORWARD (RSF) RDO PLATE?

LTT is proud to offer a limited selection of our optics footprints in a rear sight forward (RSF) configuration. Having the rear sight in front of the optic window decreases visual clutter, making it easier to remain focused on the target during the shooting process. Placing the rear sight forward of the optic also means that you can see the dot in 100% of the window, because none of your view of the optic is obstructed by the rear sight. Finally, the RSF configuration can help keep the front lens of your optic clean by deflecting some of the carbon, gas, and debris that exits the chamber away from the lens.

The following footprints are available in a rear sight forward configuration:

1. ACRO
2. RMR
3. 509T
4. EPS

NOTE: These plates will not fit on the Beretta M9A4 or 92X RDO solutions AS IT COMES from Beretta. These will only work with LTT’s proprietary RDO solution. 

Sorry, We Cannot Accept ANY Returns on RDO Plates.

Important Note Regarding RDO Plate Compatibility: This is not a comprehensive list of all the optics that may work with our plates. Our plates have been designed to fit tightly with the optic body of the main optic it was designed for. Other optics manufacturers may use the same footprint for mounting but have a different size optic body or may change the size of their optic body without warning. We cannot guarantee fit with all manufacturers that use these listed footprints.
