Optic Milling For Glock Pistols

great work and with in the time line they said. Quick response to any emails also.

These guys are lightning fast and beautifully accurate! I was amazed at the quality of machine work and rapid turnaround time by Bruce and the team at Primary machine. I have no idea how they manage to process work with such incredible efficiency, but I'll be sending more work to Primary Machine without hesitation!

Met my expectations for optic slide milling with slide cerakote - I even had some custom instructions on my order which were handled as I requested for no extra charge. Quality work, no surprises.

The best part was how fast the work was completed - I had my slide back in 7 business days from when I dropped it off at UPS, and 5 of those 7 days were for the shipping it back and forth!

This was my second slide sent to Bruce and Co. I had originally just placed an order for an optic cut for a Vortex Viper w/FO suppressor sights. In the next week I added front serrations and side pockets and then a pair of the new slide covers. Bruce was prompt with comms and my order was amended twice without issue. The slide returned in about 14 days and looks impeccable. Primary Machine is my go to for all slide work moving forward.

Out of everyone I found to, Primary Machine easily had the best pricing. Any questions I had were answered within an hour of emailing them. They received my slide on a Thursday and got my return shipping notice on Friday. I just had an RMR cut but it looks clean, and the cerakote looks smooth and applied well. They've definitely got a return customer for the foreseeable future!

Very fast turn around time and great work on installation of an RMR on my Glock 19!!!!!!

I am very please with the machining job on my Glock 35 slide with full Sarah coat finish. I would advise others to send in the whole slide with ejector, ejector rod & spring, firing pin assembly, and back plate left installed. I had already stripped my slide when I found The website for Primary Machine, so I sent it in stripped with my new Vortex Viper optic. When I got my slide back with optic mounted I had to do a little tiny bit of filing to be able to get the extractor rod in. It was no biggie, very simple. One of the Viper mounting screws had been left slightly too long, extending into the extractor rod channel of the slide.
The vortex Viper sighted in easily, and I was delighted with the groups. I sighited it in for 17 yards and the group is only a half inch low at 10 yards. That's what you get when the optic is machined in place so low on the slide. I'm a very happy customer :-).

Received my milled slide back within a week of them receiving it. They did a very nice job on the slide. Will definitely use their services again.

Sent in my Glock 19 slide and Leupold Deltapoint Pro red dot sight and primary machine did a perfect job of milling and mounting the sight to the slide in less then 2 weeks...I could not be more satisfied...thanks!
