AR15 80 Percent Lower Drill Jig

pinshape

This is a comprehensive 4-piece design tailored specifically for the AR15 lower, boasting impressive versatility as it seamlessly fits nearly all lowers and slides together with ease. The precision drill holes and meticulously milled sections are crafted according to strict Mill specifications, ensuring a flawless fit every time. In contrast, metal components often exhibit noticeable degradation over repeated use, particularly when utilizing an end mill. Notably, I've utilized the same jig on no less than five lowers before needing to replace it solely by reprinting the upper section of the design.
