Suppressor Ready Configuration
This upper ships configured for suppressor mounting compatibility. The 1/2x28 thread pitch on the barrel accepts standard AR-15 suppressor mounts, allowing you to add a suppressor when your setup is finalized. The mid-length gas system provides reliable cycling across a range of ammunition types, whether you run suppressed or unsuppressed. This configuration is designed for shooters who plan to integrate a suppressor into their final build.
Barrel and Gas System Design
The 16.5-inch barrel length paired with the mid-length gas system creates a balanced platform for both accuracy and reliability. The 1:7 twist rate stabilizes a wide range of bullet weights from 55 to 77 grains, making this upper flexible for different ammunition preferences. Chrome moly construction provides durability while the nitride finish protects against corrosion in field conditions.
Handguard and Accessory Mounting
The free float extended quad rail handguard isolates the barrel from the upper receiver, supporting consistent accuracy by removing pressure points. Quad rail design gives you four mounting surfaces for optics, lights, lasers, and other tactical accessories without requiring additional adapters. Aluminum construction keeps weight manageable while maintaining rigidity.
Build Compatibility
BCG and charging handle are not included. This upper assembly pairs with any standard AR-15 lower receiver using mil-spec trigger pin spacing. The Recoil Technologies bolt carrier group uses standard 5.56x45mm dimensions, ensuring compatibility across compatible lower platforms.
