Description

Built for shooters who demand a rock-solid foundation without the fluff, the Zero Group MFG MK 0 Stripped Receiver Set pairs a meticulously matched MK 0 stripped upper and lower receiver into one precision package. Hand-selected and fitted for optimal lock up, this set delivers tight, crisp engagement with minimal play—giving your build the rock-steady performance it deserves right from the start.

Each receiver is precision-machined from premium American-made 7075-T651 forged aluminum to exceed Mil-Spec tolerances, then finished with a durable Class 2 Type 3 hard coat anodize for superior wear resistance and corrosion protection. The lower features a flared magwell for fast repeatable reloads, while the upper comes equipped with M4 feed ramps for reliable feeding across a wide range of ammunition and magazines.

Whether you’re assembling a no-nonsense workhorse range rifle, a dependable duty build, or a custom competition gun, the MK 0 Receiver Set provides the high-strength, versatile platform you need to create something truly reliable. Proudly made in the USA by Zero Group MFG—tools of the trade for those who count on their gear.
