The AR-15 for Sale

The AR-15, or “America’s gun”, is the most popular gun in the U. S.. The AR-15 is a semi-automatic rifle meaning each time you pull the trigger one shot is fired. AR-15 is not an acronym for the assault rifle, it is an acronym for ArmaLite Rifle Model 15 referring to its original manufacturer, ArmaLite. The AR 15 for sale was not available until 1963.

In 1959, ArmaLite sold its AR 15 design to Colt, who modified it and sold it as the M-16 rifle. In 1963 when Colt developed the civilian semi-automatic version of the M-16 rifle to the public it was called the AR 15. Technically, only the Colt product is an AR-15 though variants of the firearm are produced by various manufacturers.

AR-15 Specs

The AR-15 style of rifles’ extreme popularity is mainly due to its versatility. Before the AR15, shooters would have a separate gun for every purpose. The AR-15 for sale changed this necessity for an individual gun for each purpose. It is easily customized with parts and accessories allowing the user to customize the AR15 to the degree of choice, allowing one gun to be used for different uses.

While versatility is the top reason for its popularity, the AR15 is also reliable, accurate, light-weight, and easy to shoot. All are reasons why the AR 15 for sale is popular not only with civilians, but law enforcement and security personnel.

Gas Piston Systems

The AR is available with a gas piston system, or the direct impingement system (DI/DGI). There are pros and cons to both systems, and selection is a matter of individual preference. Gas piston systems operate cleaner and cooler, providing a longer service life and less breakage from heat, wear and tear. This is in part related to the systems need for less lubrication, keeping in mind lubrication attracts more grit and grime which contributes to wear.

Gas piston systems are the more reliable of the two systems, especially when chambered with 5.56 NATO in short barrel receivers. In general, the gas piston system will run a wider variety of ammunition with fewer problems than the direct impingement system. Proprietary gas piston systems aside, other components of the AR-15 for sale in general among major manufacturers are MIL-SPEC, and will interchange with the direct impingement system variant weapons.

The largest con to using a proprietary gas piston system is the fact it is may not be user friendly. That means when it needs repair or an upgrade, you will have to send it back to the manufacturer. The other cons to a gas piston system is it will increase the gun’s weight and the current limited availability of the AR-15 for sale with gas piston systems. The gas piston not only increases the gun’s weight, but the barrel is thicker to compensate for the increased torque of the gas piston system.

Direct Impingement System

The greatest advantage of the direct impingement (DGI) gas operated system is its user friendly status. If you have a working knowledge of guns, this system provides a wider availability of parts for do-it-yourself gun owners. The DGI system also has the advantage of being lighter, as it lacks the piston and the need for a heavier barrel.

The main disadvantage of the DGI system is the limit of ammunition. Another disadvantage is, due to its cycling action, it contributes to a dirty gun. It simply requires more cleaning and maintenance than a gas piston system.
