FN 15 Military Collector M4 Stripped Lower Receiver

FN 15 Military Collector M4 Stripped Lower Receiver

This stripped lower receiver represents FN's commitment to authenticity and precision manufacturing. Built to the same exacting standards as FN's U.S. Military production carbines, it serves as the foundation for a genuine M4 or M16 build.

Construction & Materials

• Forged 7075-T6 aluminum for strength and durability
• MIL-SPEC machined and broached to precise military standards
• Hard-anodized finish in black for corrosion resistance
• Includes authentic FN military production markings

Design Features

The fire control housing is modified for semi-automatic operation only, making it compliant with civilian regulations while maintaining the authentic appearance and handling characteristics of military-issue carbines. This is the closest civilian reproduction to original DoD contract M4 and M16 receivers.

What You're Getting

A stripped lower receiver—the regulated component that forms the heart of your build. You'll need to add your own upper receiver, bolt carrier group, and other components to complete your rifle. This approach gives you complete control over your final configuration and allows you to build exactly the rifle you want.

Whether you're building a faithful reproduction of a military carbine or creating a personalized platform, this FN receiver provides the quality foundation serious builders demand.
