Design The Ultimate 5Step Smith & Wesson 22Lr Ar

The Smith & Wesson M&P15-22 is a popular choice for those looking to build an AR-style rifle chambered in .22LR. This rifle offers an affordable and fun shooting experience, making it ideal for plinking, training, and even competition. In this guide, we will walk you through the process of designing and building your ultimate Smith & Wesson M&P15-22 AR, covering every step from selecting the right parts to final assembly.

Step 1: Choose Your Lower Receiver

The lower receiver is the foundation of your AR build. For the M&P15-22, you have a few options to consider:

• Standard Lower Receiver: This is the basic option, offering a simple and reliable platform. It comes with the standard fire control group (FCG) and all the necessary components for a functional rifle.
• Stripped Lower Receiver: If you want more customization, a stripped lower allows you to choose your own FCG and other parts. This gives you control over the trigger pull, safety, and other features.
• Complete Lower Receiver Kit: For a more convenient option, you can opt for a complete lower receiver kit. These kits include all the necessary parts, such as the FCG, buffer tube, and stock, saving you time and ensuring compatibility.

When selecting your lower receiver, consider your budget, desired features, and level of customization. Research and choose a reputable manufacturer to ensure the best quality and performance.

Step 2: Select Your Upper Receiver

The upper receiver is responsible for housing the barrel, bolt carrier group, and other critical components. Here are some considerations for choosing the right upper:

• Barrel Length: The M&P15-22 is available in various barrel lengths, typically ranging from 10.5" to 16". Shorter barrels offer better maneuverability, while longer barrels provide increased velocity and accuracy. Choose a length that suits your shooting needs and preferences.
• Handguard: The handguard not only provides a comfortable grip but also allows for accessory attachment. Consider a free-float handguard for better accuracy and the ability to mount optics and lights.
• Gas System: The M&P15-22 uses a direct impingement gas system, which is simple and reliable. Ensure that the upper receiver you choose is compatible with this system.
• Rail System: If you plan to add optics or sights, opt for an upper receiver with a Picatinny rail system. This provides a stable mounting platform for your accessories.

When selecting your upper receiver, pay attention to the overall build quality and compatibility with your chosen lower receiver.

Step 3: Choose Your Fire Control Group (FCG)

The FCG, also known as the trigger group, is a critical component that determines the feel and performance of your rifle. Here are some factors to consider:

• Trigger Pull: Look for a trigger that offers a crisp and consistent pull. The M&P15-22 is known for its smooth triggers, but you can further customize it to your preference.
• Safety Selector: Choose a safety selector that is comfortable and easy to manipulate. Some options offer ambidextrous controls, making it suitable for left-handed shooters.
• Mag Release: A well-designed mag release button ensures smooth and efficient magazine changes. Look for a button that is easy to reach and operate.
• Bolt Catch: The bolt catch allows you to lock the bolt open for reloading. Consider a bolt catch that is intuitive and provides a positive engagement.

Research and compare different FCG options to find the one that best suits your shooting style and preferences.

Step 4: Pick Your Stock and Buffer System

The stock and buffer system play a crucial role in the ergonomics and recoil management of your rifle. Here's what you need to know:

• Stock: Choose a stock that provides a comfortable cheek weld and fits your shooting position. Adjustable stocks offer versatility, allowing you to customize the length of pull to your body type.
• Buffer Tube: The buffer tube is responsible for housing the buffer and spring, which absorb the recoil and manage the bolt carrier group's movement. Ensure that your chosen stock is compatible with the buffer tube system of your lower receiver.
• Buffer Weight: Different buffer weights can affect the recoil impulse and overall feel of the rifle. Heavier buffers tend to reduce felt recoil, while lighter buffers can result in a snappier recoil impulse.

Experiment with different stock and buffer combinations to find the setup that provides the best balance of comfort and recoil management.

Step 5: Add Accessories and Optics

Now it's time to personalize your M&P15-22 with accessories and optics. Here are some popular options:

• Optics: Choose a quality optic that suits your shooting needs. Red dot sights are popular for their fast target acquisition, while magnified scopes offer increased precision at longer ranges.
• Grips and Foregrips: Upgrade your grip with ergonomic pistol grips and vertical foregrips for better control and stability.
• Sling: A comfortable and adjustable sling can greatly enhance your shooting experience, allowing for easy carry and quick transitions.
• Magazine Well: Consider adding a magazine well extension to make magazine changes faster and more intuitive.
• Lights and Lasers: If you plan to use your rifle for home defense or low-light shooting, adding a tactical light or laser can greatly improve your accuracy and target identification.

When selecting accessories, ensure they are compatible with your rifle's platform and rail system. Experiment with different setups to find the combination that enhances your shooting performance.

Final Assembly and Testing

Once you have gathered all the necessary parts, it's time to assemble your M&P15-22. Follow these steps for a successful build:

1. Start by assembling the lower receiver, installing the FCG, buffer tube, and stock.
2. Attach the upper receiver to the lower, ensuring a tight and secure fit.
3. Install the bolt carrier group and ensure proper functioning.
4. Mount your chosen optics and accessories, following the manufacturer's instructions.
5. Load a magazine and perform a function check, making sure all components operate smoothly.
6. Head to the range and test your rifle's performance. Pay attention to accuracy, reliability, and recoil management.

During the testing phase, make any necessary adjustments and fine-tune your rifle to achieve optimal performance. Experiment with different ammunition types to find the best combination for your build.

With your custom-built M&P15-22, you'll have a reliable and accurate rifle that suits your shooting style and preferences. Remember to always follow proper safety protocols and regulations when handling firearms.
