    Posted by on Jun 1st 2017

    Went online, went through the Gallery, looked at the choices of slide cut options, picked the cerakote color option, optic melt,,iron sight choice to co witness, hit add to cart, sent my slide and optic via UPS, month later, the best machine work I seen!!! Very impressed, will be sending another firearm in the very near future

  2. Expert Machining and Finish - Looks fantastic! 5 Star Review

    Posted by on May 9th 2017

    After doing some research on the web for Glock modifications I chose Primary Machine - My primary goal was to have an optical sight installed but the Extreem cut looked so good in the examples on their web site that I decided to go for it. Needless to say I was not disappointed. Not only was the optical sight expertly installed, the Extreem cuts and treatment looks amazing - Expert machining and finishing work all the way!!
