    Outstanding! I started off with the 19x slide job and it was perfect. I then sent in my G20 for RMR cut and cerakote and it was also perfect. I found an overpriced 407k on ebay and asked ZR if they would mill the slide and install the optic and they did another banger job. Highly recommend. That’s my slide in the product photo and I could not be happier.

    I live locally and dropped off my P10C for a RMS cut and cerakote, and I was stunned by the quality of work. Plus, they completed the job in less than 24-hrs. ZRTS did an amazing job. I would highly recommend them for sight milling. I am very pleased.
