ZRO Delta Zulu2 223 Wylde 16" AR-15 Complete Upper w/ 15" Handguard

The ZRO Delta Zulu2 delivers precision-engineered performance in a complete AR-15 upper receiver chambered in 223 Wylde. This 16-inch configuration combines match-grade accuracy with tactical versatility through its integrated 15-inch handguard system.

What Makes This Different

The 223 Wylde chamber specification allows this upper to fire both .223 Remington and 5.56 NATO ammunition while maintaining superior accuracy compared to standard 5.56 chambers. The 16-inch barrel length provides optimal velocity for most applications while remaining compact enough for close-quarters work. ZRO Delta's manufacturing tolerances exceed mil-spec requirements, with headspace held to ±0.002 inches.

Key Features

• 223 Wylde chamber for enhanced accuracy with .223 and 5.56 ammunition
• 16-inch chrome moly vanadium barrel with 1:8 twist rate
• 15-inch M-LOK compatible handguard with full-length top rail
• Forged 7075-T6 aluminum upper receiver with M4 feed ramps
• Low-profile gas block with carbine-length gas system

Field testing demonstrates consistent sub-MOA accuracy with match ammunition, while maintaining reliable function with standard ball rounds. The carbine gas system cycles smoothly across temperature extremes from -20°F to 140°F. Competition shooters appreciate the extended sight radius, while tactical users benefit from the lightweight profile that reduces fatigue during extended carry. The M-LOK handguard accepts accessories at the 3, 6, and 9 o'clock positions without additional rail sections.
