Product Description

Performance Based Uppers for Your AR-15 and M-16

At X Products we believe in “Specification Driven” performance systems that are built to achieve the best results when paired with proper ammo and components. We use components that interact with each other without unnecessary proprietary hardware. This allows for high modularity and compatibility with common Mil Standard parts. This permits the end user to easily work on their firearm using Mil Standard wrenches and off the shelf tools.

Our line of enhanced uppers includes a 4140 or 4150 chrome-moly salt bath nitride barrel that ensure continued accuracy in high round count applications. This line of assembled uppers features our Viper Rail system which offers complete modularity, significant weight reduction, and one of the most stable attachment interfaces all while being mounted to a mil standard barrel nut. Our uppers are hammer forged on 7075-T6 aluminum and machined to exact M4 tolerances including feed ramps and rail markings for indexing optics. Each upper is discretely marked with our manufacturing information and LOT number to ensure quality control. We offer our upper assemblies with precisely indexed gas systems to ensure proper capture of gasses and consistent impingement of the action. Each gas system is fitted with a stainless steel gas tube. All uppers include a forward assist, barrel nut, barrel, gas system, and forend rail. We do not include a flash brake unless specified at bottom of page, bolt and carrier group (these will work with any mil standard bolt and charging handle). Available in Cerakote FDE or black anodizing, all uppers include X Products no-hassle lifetime warranty.

All complete uppers are built-to-order. Expect all complete uppers to ship within 10-14 days of payment.
