FN America, FN15 Military Collector, Stripped Lower Receiver 20-100821

Tailored after FN's production of U.S. Military issued carbines
and made to FN's exacting specification, 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 of 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.
