Understanding the Parts Diagram
A parts diagram is an essential resource for any owner of the Smith and Wesson MP 15. It provides a detailed illustration of each component, making it easier to identify and understand how they fit together. Here’s a breakdown of the key sections typically included in a parts diagram:
Upper Receiver Assembly
The upper receiver houses several critical components of the MP 15:
1. Barrel: The barrel is responsible for directing the bullet and is a key factor in the rifle's accuracy.
2. Gas System: The gas block and gas tube collect gas from the fired cartridge to cycle the action.
3. Bolt Carrier Group: This includes the bolt, carrier, and firing pin, which are essential for chambering and firing a round.
4. Ejection Port: This allows spent casings to exit the rifle after firing.
Lower Receiver Assembly
The lower receiver is the firearm's serialized part and includes several important components:
1. Trigger Group: Comprising the trigger, hammer, and associated springs, the trigger group controls the firing mechanism.
2. Pistol Grip: This part allows the shooter to hold and control the rifle comfortably.
3. Stock Assembly: The stock provides stability and support when aiming and shooting.

Importance of Each Component
Understanding the role of each component in the Smith and Wesson MP 15 is vital for both maintenance and operation. Here’s a closer look at some of the key parts and their functions:
Barrel
The barrel's quality significantly influences the rifle's accuracy and performance. A well-made barrel can improve bullet stability and reduce fluctuations in velocity, leading to tighter groupings on target.
Gas Block and System
The gas system is crucial for semi-automatic operation. When a round is fired, gas is redirected through the gas block into the gas tube, cycling the bolt carrier group. A malfunction in this system can lead to failures to eject or feed.
Bolt Carrier Group
The bolt carrier group (BCG) is often referred to as the heart of the rifle. It is responsible for chambering, firing, and ejecting rounds. Regular cleaning and lubrication of the BCG are essential to ensure reliable performance.
Trigger Group
The trigger group's design affects the rifle’s shooting experience. A smooth, crisp trigger pull can enhance accuracy, making it easier to hit targets consistently.
Maintenance and Repair
Proper maintenance is crucial for ensuring the longevity and reliability of the Smith and Wesson MP 15. Familiarity with the parts diagram can significantly ease the process of cleaning, inspecting, and replacing components.
Routine Maintenance Steps
1. Cleaning: Regularly clean the barrel, bolt carrier group, and chamber to prevent fouling and buildup.
2. Lubrication: Use appropriate gun oils to lubricate moving parts, especially in the bolt carrier group and trigger assembly.
3. Inspection: Routinely check for wear and tear on key components like the gas system and trigger group.
4. Replacement: Replace worn parts as necessary, following the parts diagram to ensure correct installation.
Common Repairs
- Replacing the Firing Pin: If the rifle experiences misfires, it may be necessary to replace the firing pin.
- Adjusting the Gas Block: If the rifle fails to cycle, adjusting the gas block can ensure proper gas flow.
- Trigger Adjustment: Some users may prefer a lighter or heavier trigger pull, requiring adjustments or component replacements.
