Q Sugar Weasel Complete AR-15 Upper Receiver - 5.56 - 13" - Tan

The Q Sugar Weasel Complete AR-15 Upper Receiver in Tan pairs a 13" tapered 5.56 NATO barrel with a Tan M-LOK handguard, built as a factory replacement upper or the start of a custom build.

Features:

• 13" 5.56 NATO tapered barrel, 1:7 twist
• 1/2x28 threaded muzzle, Cherry Bomb muzzle brake installed
• Carbine-length gas system, adjustable gas block
• Cerakote finished upper receiver
• Tan-finished M-LOK handguard
• Bolt carrier group and charging handle included

The 1:7 twist stabilizes the full range of 5.56 bullet weights, and the adjustable gas block paired with the carbine-length system lets you fine-tune cycling across different loads. The Cherry Bomb muzzle brake gives you quick, tool-free attachment for compatible suppressors, whether you're replacing a Sugar Weasel upper or building something custom.

Because this 13" 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.

This upper mounts to any mil-spec AR-15 lower and ships with the bolt carrier group and charging handle already in place, ready to run.

Q builds the Sugar Weasel and its complete uppers to work as a matched system, giving builders a drop-in replacement path or a starting point for a custom suppressor-host build.
