Understanding the various components of the S&W AR-15 is crucial for both new and experienced shooters. This guide will delve into the different parts of the S&W AR-15, providing you with a detailed look at each component and its function.
Receiver
The receiver is the central part of the S&W AR-15, serving as the frame that holds all the other components together. It is typically made of aluminum or steel and is available in various calibers. The receiver is where the magazine is inserted, and it also houses the bolt carrier group, which is responsible for cycling the firearm.
Bolt Carrier Group
The bolt carrier group is a critical component of the S&W AR-15, as it is responsible for the cycling of the firearm. It includes the bolt, carrier, gas key, and firing pin. The bolt carrier group moves back and forth, extracting the spent casing, chambering a new round, and then pushing the bolt forward to fire the round.
Barrel
The barrel is the tube through which the bullet travels before exiting the firearm. It is typically made of stainless steel or aluminum and is available in various lengths and calibers. The barrel’s rifling pattern is what gives the bullet spin, which is essential for accuracy and stability.
Gas System
The gas system is responsible for controlling the amount of gas that is bled from the barrel to cycle the firearm. There are three main types of gas systems: direct impingement, gas piston, and short stroke gas piston. Each system has its own advantages and disadvantages, and the choice of gas system can affect the overall performance of the firearm.
Handguard
The handguard is the part of the firearm that is held in the shooter’s hands. It provides a place to grip the firearm and also protects the barrel from damage. Handguards come in various materials, such as aluminum, polymer, and carbon fiber, and can be customized with various attachments, such as Picatinny rails.
Stock
The stock is the part of the firearm that is used to support the shooter’s shoulder. It can be adjusted for length of pull and cheek weld, which can help improve comfort and accuracy. Stocks come in various materials, such as wood, polymer, and composite, and can be customized with various features, such as cheek risers and recoil pads.
Trigger Group
The trigger group is responsible for the firing of the firearm. It includes the trigger, hammer, sear, and disconnect. The trigger pull weight can vary, and some shooters prefer a lighter trigger for faster follow-up shots. The trigger group can be replaced or upgraded to improve the overall performance of the firearm.
Magazine
The magazine is the part of the firearm that holds the ammunition. It is inserted into the receiver and is held in place by a magazine catch. Magazines come in various capacities and materials, such as steel, aluminum, and polymer. The choice of magazine can affect the overall performance and reliability of the firearm.
