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.

NOTE: HK USP Models with adjustable, factory installed rear sights cannot be cut for LTT's LOW RDO due to the geometry & depth of the adjustable sight slide cut. Please see the last photo on this page if you are unsure if your USP has factory adjustable rear sights.
Potentially affected pistols are the HK USP Elite, Expert, Tactical, & Compact models.

LTT cannot accept or work on firearms that have already received third party customization or gunsmithing to the integral parts of the firearm’s action.
This includes but is not limited to the trigger and fire control mechanism, the barrel, firing pin, or any safety components, or slides previously cut for red dot by another vendor. If you are unsure about the status of your firearm, please call us to confirm.
