The Daniel Defense Contract Overrun URG in 5.56 NATO (brand part no. WEBGB-07419-URG) is a complete upper receiver group built around an 11.5-inch Government-profile barrel. Daniel Defense designed it for special operations use. A carbine-length gas system keeps cycling smooth, and a DD4 7.0 M-LOK rail gives you room for accessories without adding much weight. The group comes together with a front sight post, a rear sight, an M16-profile bolt carrier group and a Grip-N-Rip charging handle, and the muzzle carries a DD A2 flash hider. It suits a compact, close-quarters build that needs very little added to it.

Key Specifications

• Barrel length is 11.5 inches, a short Government-profile barrel that keeps the upper compact and quick to handle.
• The cartridge is 5.56 NATO, the standard chambering for this class of AR-15 upper.
• Rifling twist is 1:7, a rate that is common for stabilizing a wide range of 5.56 bullet weights.
• The gas system is carbine length, which Daniel Defense pairs with this barrel for reliable cycling.
• The handguard is the DD4 7.0 M-LOK rail, a custom 7-inch free-float design with M-LOK slots for accessories.
