    UCC V3 cut Glock 19 Gen 5

    Posted by JONATHAN VERGARA on Oct 28th 2017

    I cannot be more happy about the work that was done on my slide! I modified my order to omit the window on top of the slide and add serrations. It looks outstanding! Cuts are smoothed and finished. The RMR cut is very precise and the cerakote job is perfect. The lead time was very impressive as well! They received my slide on a Monday, and the next Monday they were shipping it!
    I will definitely recommend them first for any slide work!

    UCC V3 on Glock 19 Gen 5

    Got this cut on my glock 19, gen 5 in sniper grey. The cuts are high quality and smooth - i don't see any sharp edges or imperfections. The slide feels significantly lighter over stock and man this thing looks awesome on my gun

    Outstanding Service and Equally matched Customer Service!

    Posted by Mike Nguyen on Aug 28th 2017

    After shopping around for slide/optics cut, I was able to message and speak with the Primary Machine team, where they helped answered all of my questions, leaving me reassured that they were a legitimate and professional business, not some guy with a dremel making slide cuts.

    Words like impressed and astonished are barely able to describe how I felt when I gotten my slide back! Their workmanship shines thru! Very happy with how everything is milled with precision and cerakoted. I had cerakote jobs done by a "basement gunsmith" which turned out crappy.

    Took less than 3 weeks from start to finish and worth the research, time, and money spent on it!

    The team at Primary Machine is LEGIT!!!

    These guys take pride in the amazing work they do.

    Got my slide back in 2 weeks from the date I shipped it. Damn... was my first impression. They do amazing work for the best price I've seen around. I didn't "settle" with primary machine for the low price and fast turn around, I went with them because they had the cut I was looking around for. Their machine work was beautiful and the cerakote was so smooth and beautiful I kept wondering if it was dlc/pvd but it's not, that's just how good they lay down a free cerakote job. I'll be sending more of my glocks in. Thank you primary machine

    Amazing Work!

    Posted by Warren on Jun 17th 2017

    Just got my slide back in the mail. Had the UCC V3 cut done to my G19 Gen 4 slide as well as some engraving. I never write reviews for anything but the finish on this product is exactly what I was hoping for- it's nothing less than perfect. Superior quality and excellent customer service from Primary Machine, you guys are awesome!

    Primary machine set the bar high!!

    Very competitive price, turn around time is just quick, don't let the quick turn around time fool you when it comes to quality work, work was flawless and the cerakote was just exactly what I wanted , magwell was sent to match as well. Love my 3 open windows on my slide. Only gripe is I wish their logo was bigger because I want the world to know the company who did my mill and cerakote work. As of now I have a death grip on my g17 because I can't stop looking at it. I also have their stealth comp on my barrel. They installed my new suppressor sight and came to me in a nice foam inside the box , got to love the American flag sticker on it. Made in America and proud of it. They'll be getting my g19 shortly for matching slide work and cerakote!!

    The price is competitive, the turn around timewas only 3 weeks and they disassembled, reassembled and installed sights on my slide for free! You can't beat this deal!
