Impeccable machining, and tight tolerances are ZEV Technologies specialty.
The ZEV Technologies Forged AR-15 Upper Receiver comes stripped, and ready for your next custom AR build. ZEV starts with high-quality 7075 T6 aluminum forgings, and final machines them to better than mil-spec dimensions held to ±.001″ tolerances, giving you maximum compatibility with mil-spec, and aftermarket parts and accessories. These uppers are thermal fit, meaning the upper receiver needs to be heated, which will help the material expand, allowing the barrel extension to seat into the upper. This will help with the accuracy of your upper build, by keeping everything tight.
