Disadvantages and Considerations
However, before rushing to build or purchase a 7 Inch Barrel AR15 Pistol, it is crucial to acknowledge its inherent limitations. The advantages come with a price, and there are several key disadvantages to consider.
Reduced Ballistic Performance
One of the most significant drawbacks of a seven-inch barrel is reduced ballistic performance. A shorter barrel means less time for the expanding gases to propel the bullet. This results in lower muzzle velocity compared to longer-barreled rifles, leading to a flatter trajectory and greater energy drop over distance. This reduced velocity also affects the bullet’s terminal ballistics, potentially impacting its effectiveness upon impact.
Reduced Effective Range
The reduced velocity translates directly into a decrease in effective range. While the AR15 platform is known for accuracy, the limited range of a 7 Inch Barrel AR15 Pistol necessitates a realistic assessment of its application. It is not designed for long-range precision shooting. The shooter will need to be aware that the ballistics of their ammunition of choice are very crucial when deploying the firearm.
Increased Muzzle Blast and Flash
The muzzle blast and flash are often more pronounced with a shorter barrel. The rapidly expanding gases have less time to dissipate before exiting the muzzle, resulting in a louder report and a more intense muzzle flash. This can be disorienting in low-light conditions and may require the use of specialized muzzle devices to mitigate these effects. Even when using a suppressor, the short barrel will still produce more flash than a longer barrel.
Recoil
Recoil can feel more pronounced with a short-barreled AR15. The reduced weight of the firearm, coupled with the potentially increased muzzle blast, can make recoil more noticeable, especially for new shooters. Proper ergonomics, including a well-designed pistol brace and good grip, are critical for managing recoil effectively.
Reliability
Potential reliability issues can also arise with a shorter barrel. The gas system in an AR15 is designed to operate with a specific barrel length and gas port location. Modifications to this system, such as the shorter barrel, can potentially lead to malfunctions if not carefully addressed. These malfunctions can involve short-stroking, failures to extract, and failures to feed. The selection of appropriate components and proper tuning of the gas system are crucial to mitigating this risk.
Legality
One of the most critical aspects of owning an AR15 pistol is understanding and complying with all applicable laws and regulations. The legal landscape surrounding AR15 pistols, including the 7 Inch Barrel AR15 Pistol, varies significantly depending on your location. Federal, state, and local laws all play a role.
Federal law defines the parameters of what constitutes a handgun, rifle, or short-barreled rifle (SBR). An SBR typically requires registration with the Bureau of Alcohol, Tobacco, Firearms, and Explosives (ATF) and involves additional requirements, such as a background check and the payment of a tax. The term “pistol” has specific connotations under federal law, and the presence of a stabilizing brace, rather than a stock, is one of the key factors that define an AR15 configuration as a pistol, not a rifle, that is not regulated under the National Firearms Act (NFA).
State and local regulations further complicate matters. Some states have more restrictive laws regarding AR15 pistols than others. It is imperative to thoroughly research and understand the laws in your specific jurisdiction before purchasing or building a 7 Inch Barrel AR15 Pistol. This research may involve consulting with a qualified legal professional or thoroughly reviewing the relevant state and local statutes.
Components and Build Considerations
Building a 7 Inch Barrel AR15 Pistol requires a careful selection of components and attention to detail. While the modularity of the AR15 platform makes it relatively easy to customize, it’s crucial to choose high-quality parts and ensure proper assembly.
Upper Receiver
The upper receiver, often a matched set with the barrel and handguard, provides the foundational structure.
Lower Receiver
The lower receiver forms the base of the firearm and houses the trigger assembly, magazine release, and other critical components. The lower receiver determines whether the build will be designated a pistol or a rifle, so it is imperative to follow your local laws when selecting this component.
Barrel and Gas System
The barrel and gas system are central to the performance of the firearm. A seven-inch barrel is the defining feature, while the gas block and gas tube work in conjunction to cycle the action. The gas port size must be appropriately sized for a short-barreled AR15 to function reliably. This size may need to be adjusted if a suppressor is going to be installed on the firearm.
Bolt Carrier Group
The bolt carrier group (BCG) is responsible for extracting, ejecting, and chambering rounds. High-quality BCGs are essential for reliable operation, especially with short-barreled AR15s.
Muzzle Devices
Muzzle devices can play a critical role in controlling muzzle flash and blast. Flash hiders, compensators, and muzzle brakes are all options, each offering different benefits. The selection of a muzzle device depends on your intended use and personal preferences.
Pistol Brace
The pistol brace is a critical component of an AR15 pistol, providing a point of contact for the shooter’s forearm to aid in stability. The type and configuration of the brace play an important role in handling and comfort.
