During the mid-1960s, the Department of Defense began a new department, the Advanced Research Projects Agency (ARPA). This agency's mission was to develop technological solutions for guerrilla warfare. Its first purchase was a small number of AR-15 rifles for testing in Vietnam. The results were impressive and the new weapon proved to be the best selling firearm in the country after the ban on its manufacture was lifted.
The most important factor in an AR rifle is the barrel. The length, material and twist rate of the barrel will dictate how accurate the gun is, and if it can be safely stored for long periods of time. Its weight also has to be taken into consideration, as well as its heat and warp resistance.
Another important factor is the bolt carrier group, which holds the firing pin and the bolt. The carrier group has to be light enough to be used in a carbine, but strong enough to withstand repeated firing. Most bolt carriers are M16 (full auto) style, although some are more versatile and can be used in pistols as well. In addition, some have a gas system that can be customized.
The best AR-15's have an ergonomic design, including a direct impingement system that prevents debris from entering the action. In addition, the best AR-15's will also have a rail system for attaching accessories. These are the most practical and useful features for any weapon.
The best AR-15's will also have programmable triggers, which can be used to increase or decrease the muzzle velocity, depending on the need. Among other things, they will also have an adjustable gas block to regulate the amount of gas used by the weapon. They are also available in several calibers, including the 5.56mm NATO and the 9mm NATO.
The best AR-15's also have a modular design, which allows for upgrades and customization. This will help ensure that the rifle you purchase will perform well for the most part. In addition, many AR's come with an extended stock, which is useful when you are hunting or in the field. In addition, the best AR's are available in a wide variety of colors, from OD green to a rusty orange.
The best AR15's will also have a solid two-year warranty, which is important if you plan to spend a lot of time on the range. They will also hold up well in most situations, although it's best to keep in mind that they are not bulletproof. The best AR's are a great option for self-defense or hunting, but they may not be for everyone.
The best AR-15's also boast the smallest possible muzzle diameter. This small detail is important to keep in mind when selecting a barrel, as it can help minimize POI shifts due to barrel whip and heat. A larger diameter barrel can be a little bit more dangerous, as it can warp over time.
The best AR-15's also feature a telescopic sight, which can be a great asset when hunting or in the field. Some of the best are also incorporated with a rail system, allowing the shooter to attach optics and other accessories.
