Ati Omni Hybrid Ar15 Stripped - Polymer Upper Receiver Fde

The American Tactical Inc Omni Hybrid AR15 Stripped Polymer Upper Receiver delivers a weight-conscious foundation for custom rifle builds. Engineered from reinforced polymer with metal inserts at critical stress points, this flat-top upper weighs approximately half a pound while maintaining the structural integrity needed for sustained use. The Flat Dark Earth finish provides a neutral earth-tone option for builders coordinating their components. Shipped stripped without bolt carrier group, charging handle, or forward assist, this receiver is ready to accept your preferred parts for a personalized configuration.

American Tactical designed this upper with internal metal reinforcement inserts positioned where forces concentrate during cycling and firing. The engineered polymer construction resists corrosion without protective coatings, making it suitable for humid environments and marine applications where aluminum can oxidize. A Picatinny rail machined to mil-standard 1913 specifications runs the full length of the flat-top, accepting red dots, magnified optics, and backup iron sights without adapters. The receiver is compatible with standard mil-spec lower receivers and accepts common dust covers. Multi-caliber capability supports builds in 5.56mm, .300 Blackout, 6.8 Special Purpose Cartridge, and .22 Long Rifle with appropriate barrel and bolt combinations.

Builders focused on reducing overall rifle weight for patrol carbines, competition setups, or extended carry applications will find measurable benefit in this polymer construction. The stripped configuration allows pairing with your choice of bolt carrier group and charging handle from our parts and accessories selection. Law enforcement agencies and training programs have adopted polymer-receiver platforms for weight reduction during high-volume training days. We stock this upper alongside complete lower receivers for those building from scratch or upgrading existing platforms.
