Please confirm your optic's footprint PRIOR to placing your order, as we cannot accept ANY returns on RDO plates. Note: Our plates will not work in conjunction with ANY other adapter plates.

For the LTT RDO Solution for Beretta PX4, we currently have options for the RMR/SRO, the Doctor Optic/Noblex family of optics, the Holosun 509T, the Delta Point Pro, EPS. When you purchase a plate, the mounting screws as listed below are included. 

NOTE: These plates will not fit on the Beretta PX4 RDO solution AS IT COMES from Beretta. These will only work with LTT’s proprietary RDO solution. 

Q: Can I buy a secondary slide with the LTT RDO solution for my PX4?

A: No, there are no additional slides available for PX4 models at this time.

 

Q: What is the co-witness of the RDO BUIS?

A: The LTT RDO included front & rear BUIS is a lower-1/3rd co-witness depending on the optic, different optics will affect the co-witness position.

 

Q: Can you cut my PX4 SubCompact for RDO?
A: No, there is not enough space on the slide for our RDO solution cut.

 

Q: What red dot optics are supported by the LTT RDO Solution?

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.

Some customers have reported the Jagerwerks SRO Shroud will fit on our system, however we have not confirmed this. Customers using this or other shrouds that add height between the adapter plate and the optic should be aware that they MAY or MAY NOT need longer/taller screws to get full thread interface - LTT does not carry longer screws.
