This is a SERVICE for us to machine YOUR slide for a Trijicon RMR sight. This service is for H&K Models (Select from the list).  Our cut is compatible with Trijicon RMR, SRO,Holosun 507C, or 508 sight. The threads are THREADMILLED, not tapped for perfect 6-32 cap screw retention.

**We do NOT currently Mill the HK45 or P30/P30L

** We are NOT machining USP9 or USP9C slides due to the lightening cuts on the bottom side. There is not enough material to cut for the RMR.

NOTE: Rear adjustable sights on the USP are not compatible with this cut.


Your slide will be returned to you with unfinished machined surfaces. If you would like to have your slide re-finished, you can choose from one of our stock Cerakote colors for an additional $75.  Click here to view Cerakote’s full color catalog.

    Speedy turnaround. I sent off to have my HK USP .45 slide to have an RMR cut and was literally sent back the same day it arrived. The optic cut was a perfect fit for my Swampfox optic. I was very happy with the service and look forward to sending more products in the future.

    Sent my USP Compact in for an RMR cut and received my finished product in a week. The job was done quickly and precise, I couldn’t be happier. Big thanks go out to ZR Tactical and I’ll be sending any future HK slide work to them as well.

    Had a stainless USP 45 and USP Tactical cut for RMR, great results. They also took on the work of cutting for an ACRO P2 for my Mark 23 after multiple other places turned me down. I couldn’t be happier with the results.

    Pricing was very reasonable and turn around time on all 3 slides was rapid, highly recommended.
