At Pickett's Mill Armory, we take pride in
selling upper receivers that are crafted from the finest materials. Each of
these short-barrel rifle receivers is test-fired before shipping to ensure
quality and safety.
Our 5.56 NATO upper receiver features an M4 feed ramp flat-top receiver with feed ramps
on both the barrel extension and the upper. The 11-inch tactical free-float
keymod rail is designed to allow you to mount items and attachments while staying
off the barrel so as not to affect harmonics thus enhancing accuracy. It has a
black anodized finish that meets military specifications. Please note that this
10.5 inch upper receiver does not include a nitrided auto bolt carrier
and charging handle but they can be added. Order this upper receiver today for precision, quality and
safety you can count on.
