(60,567 posts)The shoulder stock, grip, and upper receiver assembly are all easily swapped out. You can get "uppers" with barrels from 10 inches to about 26 inches long, various different materials, thickness, rates of twist in the rifling, different fore grip configurations, rails on which all kids of sights and accessories can be mounted.
The core of the rifle, i.e. the lower receiver assembly, is what makes it legally a firearm, and even it can be configured with a variety of trigger configurations for different purposes.
In particular, the different stock makes that one look suitable for hunting, by allowing a carefully aimed shot, rather than the one in the OP, which looks designed to be short, for combat.
The one in the OP is collapsible. Those typically can be adjusted to any of four to six positions for comfort, or collapsed to its minimum size for ease of transport or storage. Anyone who shoots the rifle would normally adjust the stock to the most comfortable length for best accuracy. My state's law doesn't permit collapsible or folding stocks - Another good reason to have them interchangeable, and a variety of different types available. Changing the stock on an AR-15 takes just a few minutes. The stock is held in place by one screw.
Accuracy in combat is just as important as accuracy while hunting. You always want to shoot as accurately as possible.
