Technical Specifications
The BRN-180 Gen3 upper is engineered for shooters who demand performance without compromise. The 223 Wylde chamber is precision-machined to tighter tolerances than standard 5.56 chambers, resulting in better accuracy with both .223 and 5.56 ammunition. The short-stroke piston system keeps gas and carbon away from the bolt carrier group, enhancing reliability in adverse conditions and reducing maintenance. The 16″ barrel is made from high-quality steel with a protective finish, ensuring longevity and consistent accuracy. This blemished unit has minor cosmetic flaws that do not affect function, making it an excellent choice for budget-conscious enthusiasts.
Why Choose This Upper?
Whether you’re building a new rifle or upgrading an existing one, the BRN-180 Gen3 offers a unique blend of modern design and proven performance. The piston system is particularly beneficial for suppressed shooting, as it minimizes gas blowback. The 16″ length makes it suitable for everything from home defense to competition, while the 223 Wylde chamber maximizes versatility. As a blemished product, you save money without sacrificing quality—perfect for users who prioritize function over flawless appearance.
Installation & Compatibility
This upper receiver is designed to mate with any mil-spec AR-15 lower receiver, using a standard takedown pin. No modification is required, and it works with most AR-15 components, including triggers, stocks, and magazines. The included handguard provides ample space for accessories like optics, lights, and grips. We recommend consulting a qualified gunsmith if you’re unsure about installation, but most experienced builders will find it straightforward.
