AR 15 Upper Design

The AR 15 was designed to be modular, allowing it to be easily customized to the task at hand with different parts and accessories. Based on the fully automatic M16, AR 15 semi automatic rifles can be dismantled and reconfigured in a variety of ways by its civilian operator. While there are many configurations possible due to large amount of manufacturers creating parts and accessories, AR 15s cannot legally be converted to fully automatic weapons due to federal laws. Some manufacturers will mark their AR 15 style rifles with a faux selective-fire switch for the sake of re-enactors and collectors, but the rifle will only fire in semi automatic mode.

The upper receiver of the AR 15 is the most customizable feature of the rifle, allowing for different stock lengths, sights and different barrel variants. Many barrels offer different weights and even calibers, allowing each shooter to hand-pick their preferred ammunition. It should be noted, however, that some upper receivers with certain caliber barrels may require adjustments to the lower receiver in order to work optimally. Some companies offer strengthened AR 15 upper and lower receivers made from a solid block of aluminum rather than aluminum forging.
