Troy Industries A3 Complete AR-15 Upper Receiver - 5.56 - 11.5"

The Troy Industries A3 Complete AR-15 Upper Receiver in 5.56 pairs an 11.5" barrel with an optic-ready A3 flat-top receiver and the SOCC M-LOK handguard, a lightweight, maneuverable package built for a compact build.

Features:

• 11.5" barrel chambered in 5.56 NATO
• Optic-ready A3 flat-top upper receiver
• SOCC M-LOK handguard for accessory mounting
• Threaded barrel with muzzle device installed
• Troy Industries flip-up iron sights included
• Hardcoat anodized black finish
• Bolt carrier group and charging handle included

The SOCC M-LOK handguard gives you a generous mounting platform for lights, grips, and other accessories while keeping the overall package light and easy to maneuver, and the flip-up iron sights provide a reliable backup if your primary optic ever fails or runs out of battery.

Because this 11.5" barrel measures under 16", this complete upper is intended only for an AR pistol or a legally registered short-barreled rifle — attaching it to a standard rifle lower without the correct configuration violates federal law.

With BCG and charging handle included, this upper is ready to mount and shoot as soon as it's paired with a compatible lower and magazine.

Troy Industries builds AR-15 uppers and accessories machined from hardened aircraft aluminum, aiming for a lightweight, low-profile platform without sacrificing durability.
