Looks great!  How much did it cost, if you don't mind me asking?

The service is listed in their website. $125 + additional shipping insurance if you want it. Pretty reasonable.

In case anyone is still curious about this topic.  I just got the slide back from Patriot Defense after less than 3 wks from the time of sending the slide to them (one of the weeks being the crazy ice-pocalypse Texas endured, where someone was shutdown).  I am a noob to this, but looks to be quality craftsmanship.  The RDS is mounted very securely on the slide.  I am excited to go sight in and shoot it.  Cheers.

I found this forum post and reached out to Patriot Defense to confirm they do indeed do the optics milling work on x-calibur slides. I sent mine in along with a vortex venom. Hope to get it back in the next couple of weeks. Will post pics for those lurking that are interested.
