Q Sugar Weasel 5.56 NATO AR-15 Barrel Assembly with Charging Handle - Carbine Length - 13”

Designed for reliability and enhanced performance, the Q Sugar Weasel 13” Barrel Assembly is built to deliver exceptional results with a wide range of ammo. Crafted from stainless steel, this 5.56 NATO barrel features a carbine-length gas system and comes equipped with a fully adjustable gas block for fine-tuning your setup.

The gas block is precision-machined and secured using a jam nut, eliminating the need for set screws or taper pins and preserving the barrel’s structural integrity. Its indexed design ensures perfect alignment with the gas port, while stainless steel set screws provide “infinite” adjustment and locking capability.

Features:

• 13” stainless steel barrel chambered in 5.56 NATO
• Carbine-length gas system
• Fully adjustable stainless steel gas block
• 25° tapered muzzle for improved accessory alignment and repeatability
• Compatible with mil-spec AR-15 upper receivers
• Includes charging handle

At the muzzle, a 25° taper replaces the standard 90° shoulder to significantly improve the fit and repeatability of muzzle devices and suppressors. This taper ensures better concentricity, increased surface area for secure mounting, and consistent point-of-impact after removal and reinstallation of accessories.
