    Unlock superior performance and style with the AR-15 300 Blackout 10.5" Diamond Cut 10" M-LOK Upper Assembly from Moriarti Armaments. This high-performance upper assembly is designed for precision, reliability, and tactical versatility. Whether you're upgrading your current AR-15 or building from the ground up, this upper provides a perfect balance of recoil control, enhanced accuracy, and customizability. The sniper grey Cerakote finish and diamond-cut M-LOK handguard deliver both durability and a sleek, modern appearance.

    Key Features:

    1. 300 Blackout (300 BLK) Cartridge – Designed for versatility, the 300 Blackout chambering excels with both subsonic and supersonic ammo, providing outstanding performance in tactical, home defense, and hunting applications.

    2. 10.5" Barrel Length – The 10.5-inch barrel is perfect for close-quarters engagements, enhancing maneuverability without sacrificing power. Ideal for short-barrel AR builds, the barrel is crafted from 4150 Chrome Moly Vanadium (CMV), providing enhanced durability, strength, and accuracy.

    3. 1:7 Twist Rate – The 1:7 twist rate stabilizes a wide range of bullet weights, ensuring that each shot is fired with precision and accuracy, whether you're using heavier subsonic rounds or lighter supersonic rounds.

    4. Pistol-Length Gas System – The pistol-length gas system reduces recoil and improves the cycling speed, making it ideal for compact builds and fast follow-up shots. Low-profile gas block ensures smooth, reliable cycling in this 300 Blackout upper assembly.

    5. Slanted Muzzle Device – The slanted, steel nitride muzzle device is designed to reduce recoil and muzzle rise, providing more control and faster target acquisition. The slanted design also helps with the dispersal of gas, minimizing the felt concussion, which is a critical feature for short-barreled rifles and pistols.

    6. Diamond Cut 10" M-LOK Handguard – The 10-inch M-LOK free-floating handguard is constructed from 7075-T6 aluminum for enhanced strength and durability. Its diamond-cut design provides superior grip and aesthetics, while the M-LOK rail system offers modular flexibility for attaching various accessories like grips, lights, and lasers.

    7. Sniper Grey Cerakote Finish – The sniper grey Cerakote finish enhances the upper’s durability, ensuring resistance to corrosion, scratches, and wear while giving your firearm a sleek, tactical appearance.
