is a rifle the same as a shotgun
Shotgun Aside from the most common use against small, fast moving targets, the shotgun has several advantages when used against still targets. First, it has enormous stopping power at short range, more than nearly all handguns and many rifles. Though many believe the shotgun is a great firearm for inexperienced shooters, the truth is, at close range, the spread of shot is not very large at all, and competency in aiming is still required. A typical self-defense load of buckshot contains 8â€“27 large lead pellets, resulting in many wound tracks in the target. Also, unlike a fully jacketed rifle bullet, each pellet of shot is less likely to penetrate walls and hit bystanders.[2] It is favored by law enforcement for its low penetration and high stopping power.
Colt AR-15 Colt started selling the semi-automatic version of the M16 rifle as the Colt AR-15 in 1964.[1][2][3] The first mass production version was the Colt AR-15 Sporter, in .223 Remington, with a 20-inch barrel and issued with 5-round magazines.[2] Over the decades, Colt has made many different types of AR-15 rifle and carbine models, including the AR-15, AR-15A2, AR-15A3, AR-15A4, and many other models.
