Details

The Mandos 18-inch AR-15 complete upper build chambered in 6.5 Grendel from Davidson Defense is engineered for precision shooting. Constructed with a barrel made from durable 4150 Chrome Moly Vanadium, it features a mid-length gas system for reliable operation. The 18-inch barrel, finished in nitride and boasting a government profile with a 1:8 twist rate, maximizes accuracy while maintaining lightweight performance. The upper receiver is crafted from 7075-T6 aluminum with an anodized finish, ensuring strength and durability.

The build includes a Mil-Spec AR-15 charging handle and a complete 6.5 Grendel II QPQ Nitride bolt carrier group made of 9310 alloy steel. Compatibility with standard AR-15 lower receivers is assured. The M-Lok handguard provides versatility with features like a partial Picatinny rail, integrated handstop, and anti-rotation tabs. The muzzle is equipped with a GI birdcage flash hider threaded at 5/8x24, completing this robust upper assembly for discerning gunsmiths.
