PRODUCT DESCRIPTION
The 3KEYZ Tactical Firehound 16″ 5.56 NATO Parkerized Complete Upper delivers rugged reliability and a classic look. Built around a 16″ heavy-profile 4150 CMV barrel with a 1:9 twist and a durable parkerized finish, this upper is optimized for sustained performance. A carbine-length gas system with a micro low-profile gas block ensures reliable cycling, while a 15″ free-float M-LOK handguard offers modularity for accessories. The upper also includes a retro-style A1 three-prong compensator, a forged 7075-T6 Mil-Spec receiver, a stainless gas tube, and a full BCG + charging handle, making it a drop-in, long-lasting option for a range-ready build.
