Holosun 507k/407k Footprint Optic Cut (Also fits RMSc Optics) for Glock

(4 customer reviews)


SKU: N/A Categories: ,


This is a service to cut your factory Glock slide for a Holosun 507k/407k pattern optic (aftermarket slides cut with prior approval). The cut will be .125" deep. The front bosses WILL be milled in to locate the optic as this is the way the optic was designed to be located and this ensures universal fitment for any optic that is in spec. The threaded holes will not break into any of the internal parts of the slide. The right threaded hole will be shallower than the left so that it does not interfere with the extractor pin. The holes are threaded 6-32 and for a a 507k/407k you will need 6-32 x 3/8 screws.

**Screws will be included for free.

Recommended Sights for Lower 1/3 Co-witness: Angry Bear Arms Suppressor Height Sights OR Dawson Precision .225" Rear/ .220" Front

IRON LOCATION: You may choose to keep your irons in the factory location, which will mean the optic sits in front of the rear iron sight. We also offer an iron sight relocation service where the optic will be cut to the rear of the slide and the iron sight dovetail will be recut in front of the optic. **Please note: The Glock 42 model can be cut for this optic, but the rear iron sights will be eliminated completely.

COATINGS: There is also an option to add Cerakote or bluing to the slide. We offer the Cerakote in Graphite Black, FDE, ODG, Tungsten and Burnt Bronze and it will be applied to the entire slide. The cold bluing will be applied to just the area we cut and your factory finish will remain everywhere else. This type of finish is not as consistent and visually appealing as the Cerakote, but offers some protection for the bare metal. If the Cerakote option is chosen, we will remove your channel liner and install a new one after coating.

THE PROCESS: Once you checkout with your chosen optic cut you will receive an email with instructions on how to ship the slide to us. Please ship us your stripped slide only, we are not an FFL and cannot handle frames! We will complete the cut and/or Cerakote and then ship the slide back to you quickly! You will receive an email once the slide has been shipped back to you.

TIMELINE: Once we receive your slide, we will complete the work in 3 business days (Mon-Fri) or less and get it shipped back to you. This includes coating.

PLEASE NOTE: Your order will be returned to the address that you provide at checkout. Please follow instructions and include a copy of your confirmation email when you ship your slide to us, failure to follow this will result in increased turnaround time.

  1. Sowa

    Excellent work done here, can’t beat their turn around time or price. Great Cerakote coating. had work done on my g43x non mos slide came out perfect and works like a charm.

  2. Jamieq

    Great work and super quick as well. fit my non mos g48 perfect for a holosun 407k. I sent my slide in along with the slightly cheaper RMSc optic I had at the time and they even made sure to reshape the lug holes on the bottom of the optic just a little to adjust for the tolerances. Everything fit like a charm.

  3. Greg

    Amazing job. Perfect cut and very professional. Extremely fast turnaround, returned within the same week. I got a cut for my G19 for holosun 407k, fit perfectly. 10/10 would recommend.

  4. Grant V

    Quality milling, fantastic turn around time. Will definitely do business again.
