This service is for milling your G43/G43x/G48 for a Holosun 407K/507K, Shield RMSC/SMSC, Romeo Zero. Optic is placed in front of the rear dovetail. Optic is milled deep enough for factory sights to be used. Slide is tapped for 4mm screws. The 4mm screws that come with the optic will need to be shortened to work properly.
This service requires you send in your factory slide for the machining to be done. Fabricated Arms will disassemble and reassemble your slide if you choose to not do so yourself. Include a cover letter with your information when sending in your slide. Fabricated Arms will send the machined slide back to you when complete. Slide will be returned to you with a raw machined pocket unless you request your slide to be cerakoted. An additional cerakote service is available under the cerakote tab. It is preferred that you send your optic along with your slide to ensure proper fitment.
