This upper assembly is built on a custom billet aluminum receiver and includes a MPI-tested Nitride Bolt Carrier Group (BCG) and AR-15 Mil-Spec charging handle for reliable performance.

Key Features:

• Barrel: 4" .40 S&W barrel, crafted from 4150 CMV steel with a nitride finish for exceptional durability and strength. The 1:16 twist rate ensures accurate shots, and the 5/8x24 threads are perfect for adding muzzle devices or flash hiders.

• Muzzle Blast Diverter: This muzzle blast diverter minimizes the effect of muzzle blast, offering a more comfortable shooting experience and reducing impact on your surroundings.

• Bolt Carrier Group (BCG): The AR-40 MPI-tested Nitride Bolt Carrier Group is compatible with .40 S&W and 10mm rounds. The mag phosphate finish adds durability, making this BCG ready for action.

• Handguard: The 4" American-built custom M-LOK handguard is sleek, lightweight, and perfect for attaching accessories with ease, providing both comfort and performance in a compact design.

• Charging Handle: The AR-15 Mil-Spec charging handle is included, ensuring smooth and reliable operation.

• No LRBHO: This upper assembly does not feature the Last Round Bolt Hold Open (LRBHO) function, offering a more cost-effective design.

• Customization: Choose your color option to personalize your build and make it stand out.

Please Note: This upper assembly is sold with a BCG and charging handle but does not include a lower receiver, sights, or magazines.
