HK P30 & USP Optic Plates for LTT's LOW RDO Solution

We currently have options for the RMR/SRO, the Holosun 509T, and the Holosun EPS footprint for HK P30 and USP series pistols cut for RDO by LTT.

These plates will fit all P30, P30L, P30SK, & USP series pistols with the LTT RDO Solution.
Please Note: We do not currently have availability for the EPS front sight for USP pistols, but expect to have them soon.

Please confirm your optic's footprint PRIOR to placing your order, as we cannot accept ANY returns on RDO plates. 

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

Our RMR Plate fits:

  • Trijicon RMR
  • Trijicon SRO
  • Trijicon RMR HD
  • Holosun HS407C
  • Holosun HS507C
  • Holosun HE508T
  • Riton X3 Tactix PRD
  • NcStar VISM FlipDot Pro
  • Swampfox Kingslayer
  • RMR to Plate Screws: 
  • For attaching a Holosun to the RDO Plate use:  4x40 – 5/16
  • For attaching an RMR or SRO to the RDO Plate use: 4x40 – 3/8

Our HE509T Plate fits:

  • Holosun HE509T 

Our Holosun EPS Plate fits:

  • Holosun EPS
  • Holosun EPS Carry
  • Holosun 407k
  • Holosun 507k
  • Note: If you order this plate for your existing LTT RDO slide, you will also need the corresponding correct front sight (included with the plate). The EPS Plate uses a much lower BUIS rear sight and will not work correctly without this shorter front sight. 
  • EPS Optic to Plate Screws:
  • EPS: EPS to RDO plate use: 4x40 - 5/16

  • NOTE: We do not currently have a front sight for the USP pistols using an EPS plate.

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 the Jagerworks 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.
