This is for mounting a Holosun K-series optic (407K/507K/EPS/EPSCarry) onto an applicable Sig Sauer®. The Holosun K-series optics use there own footprint. It's a similar footprint to the RMSc, but doesn't have to rear two recoil lugs.
A standard K-series cut will be 0.125” deep into the slide and 0.050” in front of the OEM rear iron sight position. The holes will be drilled and tapped for #6-32 countersunk screws, which will be provided.
When shipping your slide, send the complete upper assembly, including the barrel and recoil spring. This will allow us to verify the fit of the red-dot against the other components. If you send the slide with new iron sights, we'll install them for free. DO NOT SEND THE LOWER PART OF YOUR FRAME.
**NOTE** Due to the design of the iron sights, there is potential of damaging them during removal, particularly the front iron sight. We'll do the best we can to protect the sights, but we will not be held responsible for replacing them if damaged. If you choose to have your rear iron relocated in front of your optic. it will be cut to a glock style iron. For the best possible service, Please inlcude or inquire about getting some new ones installed at the same time.
Please send your red dot with your slide. From our experience, every red dot is a little unique. We want to ensure you get the best possible fit.
