The butt stock is a Magpul MOE fixed model. Most AR-type rifles have adjustable stocks, but for a rifle like this, the fixed stock is a better option, in my view. The typical user of this rifle won’t be using it with body armor or adjusting the stock size for close-quarters use, but for longer range precision shooting. The fixed stock provides a better and more consistent platform to establish a consistent hold and cheek weld. Speaking of cheek weld, the top of the stock is wide and well rounded, offering a comfortable and stable platform. The stock also features multiple sling attachment points, rear monopod attachment points, and has a hollow body in case you want to stow away parts, cleaning materials or some extra bacon jerky.
