Product Info for TRYBE Defense AR-15 Complete Upper Receiver

The AR-15 complete upper receiver assembly by TRYBE Defense is engineered around proven military-inspired architecture and modern free-float design principles to deliver consistent accuracy, durability, and modular compatibility. Built for the AR-15 platform, this upper pairs a high-strength 4150 Chrome Moly Vanadium 16” steel barrel coated in corrosion-resistant nitride QPQ with a rigid 15" free-float M-LOK handguard, ensuring reliable performance under sustained fire while promoting a smoother recoil impulse and maintaining optimal weight distribution and handling. Designed to accommodate a wide range of ammunition, optics, and accessories, this complete upper receiver serves as a versatile foundation for duty, training, or general-purpose rifle builds.image

 

Versatile Performance

Built for dependable performance and modularity, this complete upper receiver assembly delivers reliable execution in a balanced, duty-ready configuration. Designed around various common barrel profiles and modern free-float architecture, it’s an ideal solution for shooters who demand consistency across training, defense, and general-purpose use. Proper BCG, recoil spring, and buffer weight are necessary to ensure proper cycling.

 

16” 4150 CMV Barrel

The heart of this upper is a 16" barrel machined from 4150 CMV steel; a material trusted in military and hard-use rifles. Compared to 4140 steel, 4150 CMV offers superior heat resistance and durability under sustained fire, making it well-suited for high round counts and demanding shooting schedules.

 

Free-Float 15" M-LOK Handguard

A 15-inch free-float M-LOK handguard maximizes usable rail space while eliminating barrel contact, improving mechanical accuracy and consistency. The extended length supports modern shooting techniques, enhances control, and provides ample real estate for accessories such as lights, grips, and bipods—without unnecessary bulk.

 

Continuous Picatinny Rail

The full-length top Picatinny rail ensures secure mounting of optics, magnifiers, backup iron sights, and night vision or thermal devices. Precise alignment and repeatable mounting make this upper well-suited for both duty and recreational setups.

 

Why the AR-15 Platform

The AR-15 remains the most versatile rifle platform available, offering unmatched modularity, parts availability, and ergonomic efficiency. This upper receiver takes full advantage of that ecosystem—allowing shooters to tailor their rifle for home defense, range use, competition, or professional applications with minimal effort.

 

Performance-Driven Design. Quality Materials. Reliable Performance.

This complete upper receiver is engineered to meet the expectations of serious AR-15 users who prioritize function, longevity, and adaptability in a single, well-balanced assembly.

 

This TRYBE Defense upper receiver is the perfect tool for any shooter serious about the performance of their AR-15 firearm.
