Guntec Ar9 Stripped Billet - Upper Receiver Black

The Guntec AR9 Stripped Billet Upper Receiver in Black is a precision-machined component designed specifically for 9mm Luger platforms, ideal for builders seeking reliability and performance in their firearm assembly. This stripped upper receiver allows users to customize their build by selecting their own bolt carrier group and charging handle, catering to those who prioritize control over their firearm configuration.

Constructed from 6061 T6 aluminum, this upper receiver offers durability and precise machining for tight tolerances. The flat-top 1913 Picatinny rail extends the full length of the receiver, providing ample optic mounting options and accessory compatibility. Its smooth slab-side design omits forward assist and dust cover provisions, reducing weight and complexity while maintaining structural integrity.

This upper receiver is particularly beneficial for sport shooting, training, or duty-configured carbines, where the advantages of 9mm ammunition, such as lower recoil and cost-effectiveness, are significant. While it is designed for 9mm AR builds, users should verify compatibility with their chosen lower receivers, as fit may vary across different manufacturers. Weighing in at just 0.73 lbs, this upper receiver adds minimal mass to your overall setup.
