AR-15 Accessories

The popular AR-15 is well known for its accuracy and reliability, but it is the versatility of the gun that is the crown of the AR-15 for sale. With the ability to exchange receivers, the AR-15 can provide multiple caliber weapon options and various configurations. The wide availability of parts and AR-15 accessories enable you to customize your AR-15 with the features you desire, and the ability to exchange parts and accessories for a different purpose in a snap.

Like a great number of rifles, the AR-15 was developed for military use, providing a durable firearm to withstand both harsh environmental conditions and heavy use. It is from this platform that today’s semi-automatic AR-15 was developed for public use.

Redesigned for the civilian market, the AR-15 has become America’s number one rifle with a continually expanding market of parts and AR-15 accessories.

Dominating in competitive matches, used for hunting, predator control, as home and perimeter defense, for target practice and used among the law enforcement and security community, the AR-15 for sale continues to enjoy a growing popularity.

The AR-15 is rapidly gaining popularity among hunters. It should be noted the standard AR-15 is a 5.56 NATO or .223 Rem, and the two rounds are not interchangeable. The .223 Remington can be used safely in a 5.56mm chamber, but it is unsafe to use the 5.56mm in a .223 chamber. The higher pressure of the 5.56mm round is too great for a .223 chamber. If you will be using 5.56mm, buy an AR-15 chambered for 5.56mm. You can use the .223 in it allowing you greater versatility; you just can’t use the other way around.

People often ask which AR-15 accessories they should have. AR-15 owners often accessorize their guns to the max, only to find it too heavy to be comfortable. Tactical lights are often added, whether they are used or not. If you will be using a tactical light after dark, it becomes a prized accessory; otherwise, just keep in mind, adding accessories will also add weight. Luckily, the AR-15s versatility also imparts ease of accessorizing, or removing them. One of the best investments in AR-15 accessories is a sling. It frees up your hands, enables you carry more and can help you to hang on to your gun.

Pay extra for the chrome lined barrel, or other lining that will extend the barrel life. Don’t use jointed cleaning rods, doing so can damage the interior finish of the rifle.

If you are going to mount a scope or other optic, select a flat top rifle or ensure you purchase a rifle with a removable carry handle. Mounting a scope will be easier.

The Truth About the AR-15 For Sale

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.

Laser Sights

If you have ever had to climb a tree because a wild boar is after you or get on top of a car while the bumper is being tore off by the dynamite porky, you will learn to appreciate lasers in low-lighting conditions as an assist in the take down of boar before they get out of the darkening woods. You can’t hunt after dark in many states, not even the vermin. Yet hogs and coyote often come no sooner than late afternoon and disappear just after the sun rises in many locations, providing a very narrow window of opportunity with wooded areas already darkening.

With so many great optics available, applying your intended use and considering your budget is the best guide for choosing optics. Tactical lights are also a great product useful for vermin control, and you will find the laser a great assist in low light conditions.
