Description
Precision meets value in this stainless steel 5.56 NATO complete upper.
This AR-15 Complete Upper is a high-value, “ready-to-run” solution for your next AR-15 build or upgrade. Chambered in 5.56 NATO, this assembly features a 16-inch M4 contour barrel crafted from 416R Stainless Steel, offering a sleek look with enhanced corrosion resistance and precision.
The barrel utilizes a 1:8 twist rate, providing excellent stability for a wide range of bullet weights, while the carbine-length gas system ensures reliable cycling. It comes equipped with a 15-inch M-LOK Split Rail, which significantly reduces weight without sacrificing attachment space for lights, grips, or lasers.
Designed for ease of use, this is a standard rear-charging model that includes both the Bolt Carrier Group (BCG) and charging handle. It is fully compatible with any mil-spec AR-15 lower receiver, making it one of the most cost-effective ways to get a stainless-steel barreled rifle onto the range.
What’s Included
This kit is not a firearm. It includes an assembled upper receiver, bolt carrier group, and charging handle.
