FN Expands FN 15 Accessory Line

FN America, LLC announces the release of FN 15® Military Collector Series M4 and M16 complete upper receiver assemblies and stripped lower receivers. For AR-15 enthusiasts, these uppers and lowers offer the unique opportunity to build an authentic M4 or M16 replica with components that are made to FN’s and the U.S. military’s exacting specifications.

FN 15 Military Collector M4 and M16 Upper Receivers

The FN 15 Military Collector Series M4 and M16 upper receiver assemblies are authentic reproductions of the original and ready to drop onto a lower receiver for immediate use. Each assembly consists of a chrome-lined, button-broached barrel with 1:7 twist rate chambered in 5.56x45mm. Its MIL-SPEC bolt is machined from Carpenter 158 steel that has been high pressure proofed and magnetic particle inspected. Completing the assembly are a Knight’s Armament rail system with adapter covers, MIL-SPEC back-up sights, and vertical foregrip for an authentic reproduction.

FN 15 Military Collector Stripped Lower Receivers

Tailored after FN’s production of U.S. Military issued carbines, the replica stripped receivers are the heart of an authentic M4 or M16 build. Forged from 7075-T6 aluminum, machined, and broached to precise MIL-SPEC standards before anodizing, each receiver includes the markings inspired by FN’s U.S. Military production M4 and M16 receivers. Although the fire control housing is modified to block select-fire operation, each semi-auto receiver is the closest reproduction to the original DoD contract carbines.
