M16 CUT LOWER RECEIVER

M16 Cut Lower Receiver: The Foundation for Authentic AR-15 Builds

For the discerning builder and enthusiast seeking to create an AR-15 that truly reflects the spirit of the iconic M16, the M16 Cut Lower Receiver stands as the ultimate foundation. This isn’t just any stripped lower; it’s a meticulously crafted component designed to replicate the internal geometry of the original M16 fire control pocket, offering a level of authenticity and compatibility that standard AR-15 lowers simply cannot match. While strictly adhering to all legal requirements for semi-automatic firearms, these lowers provide the aesthetic and functional characteristics favored by those who appreciate the historical accuracy and robust design of the military’s most renowned rifle.

The Heart of Your Build: Uncompromising Quality and Precision

The lower receiver is the serialized core of your AR-15, and its quality dictates the overall performance and reliability of your firearm.¹ Our M16 Cut Lower Receivers are forged from aerospace-grade 7075-T6 aluminum, a material renowned for its exceptional strength-to-weight ratio and resistance to stress and corrosion.² This robust foundation ensures your build can withstand the rigors of extensive use, maintaining its structural integrity and precision over countless rounds.

Every M16 Cut Lower Receiver undergoes precision CNC machining to exacting MIL-SPEC standards.³ This meticulous process ensures perfect dimensional accuracy and a flawless finish, eliminating any slop or play when mating with other components. The result is a receiver that facilitates smooth operation, optimal parts fitment, and a tight, responsive feel to your completed rifle.

The Distinct Advantage: Understanding the M16 Cut

What sets an M16 Cut Lower Receiver apart is its internal fire control pocket geometry. Unlike standard AR-15 lowers that often feature a “high shelf” or “low shelf” design to prevent the installation of certain full-auto components, the M16 cut replicates the original full-depth pocket of the M16.

It is crucial to understand that while these lowers possess the M16 pocket geometry, they are manufactured without the third hole required for automatic sear installation. This ensures they remain 100% legal for civilian ownership as a semi-automatic firearm component, fully compliant with all federal regulations.

The benefits of the M16 Cut include:

• Authentic Aesthetics: For collectors and enthusiasts seeking a historically accurate M16 clone, the internal M16 cut provides an authentic look and feel, differentiating it from standard AR-15 lowers.
• Enhanced Compatibility (within legal bounds): While not enabling full-auto functionality, the M16 cut can offer compatibility with certain drop-in auto sears (RDIAS) for licensed SOT manufacturers building post-sample machine guns, and some legacy components, without requiring additional milling (always ensuring compliance with all NFA rules). For the average civilian builder, this cut means no modification is needed for RDIAS if you are a licensed SOT.
• Optimal Fitment for Aftermarket Triggers: The more open geometry of the M16 cut can sometimes provide better clearance and easier installation for a wider range of aftermarket trigger systems, including advanced drop-in triggers, ensuring a seamless fit without interference.
• Mil-Spec Purity: For those who appreciate adherence to military specifications, the M16 cut represents a truer replication of the original M16 design.

Thoughtful Design for the Builder:

Our M16 Cut Lower Receivers are designed with the builder in mind, featuring:

• “SAFE” and “FIRE” Selector Markings: Clearly engraved selector markings ensure intuitive operation and proper safety protocols. Some models may even feature “SAFE,” “SEMI,” and “AUTO” markings for enhanced aesthetic authenticity, though the receiver remains strictly semi-automatic.
• Hardcoat Anodized Finish: A durable Mil-Spec Type III Class 2 hardcoat anodized finish provides superior resistance to abrasion, corrosion, and the elements.⁴ This rugged finish not only protects your investment but also offers a deep, non-reflective black appearance that complements any build.
• Multi-Caliber Marked: Engraved with “CAL MULTI,” these receivers are ready to host a wide array of AR-15 compatible calibers, providing maximum versatility for your build aspirations.
• Standard .154″ Trigger Pin Holes: Ensures compatibility with standard Mil-Spec and aftermarket trigger components.
• Standard .250″ Pivot and Takedown Pin Holes: Guarantees universal fitment with all Mil-Spec upper receivers.

The Foundation for Your Dream Build:

Whether you’re embarking on a faithful M16 replica, a high-performance competition rifle, or a robust duty weapon, the M16 Cut Lower Receiver provides the unparalleled foundation you need. It’s the critical component that dictates the reliability, compatibility, and ultimately, the success of your AR-15 project.
