The Smith & Wesson M&P 15-22 is a popular .22 LR training rifle, appreciated for its affordability and reliability. However, like any firearm, parts can wear out or you might simply want to customize your rifle. Replacing the upper receiver is a relatively straightforward process, opening up possibilities for upgrades and modifications. This guide will walk you through everything you need to know about M&P 15-22 upper replacement.

Why Replace Your M&P 15-22 Upper?

Several reasons might prompt you to replace your M&P 15-22 upper receiver:

  • Wear and Tear: Extensive use can lead to wear on the existing upper, potentially affecting accuracy or reliability.
  • Upgrades: Switching to an upgraded upper receiver allows for enhancements like improved sights, different barrel lengths, or even a change in the overall aesthetic. Consider upgrading to a threaded barrel for the addition of a suppressor.
  • Customization: Replacing the upper is a simple way to personalize your rifle. You can choose uppers in different finishes, materials, or with integrated accessories.
  • Damage Repair: If your current upper receiver is damaged, replacement is often the most cost-effective solution.

Choosing the Right Replacement Upper

Before purchasing a replacement upper, it's crucial to ensure compatibility. While the M&P 15-22 shares design elements with AR-15 platforms, it's essential to verify that the upper is specifically designed for the M&P 15-22. Using an incompatible upper receiver can lead to malfunctions or even damage to your firearm. Always check the manufacturer's specifications.

Factors to Consider When Choosing an Upper:

  • Material: Most uppers are constructed from aluminum alloy, offering a balance of strength and weight. Some higher-end options might utilize more durable materials like hardened steel.
  • Barrel Length: Barrel length significantly impacts accuracy and velocity. Shorter barrels are more maneuverable but may result in slightly reduced accuracy. Longer barrels usually offer greater accuracy.
  • Sights: Some uppers come with integrated sights, while others require separate sight purchases. Consider your shooting style and preference when selecting a sight system.
  • Finish: Uppers are available in various finishes, including anodized black, Cerakote, and others. This choice affects the appearance and durability of your rifle.

The Replacement Process: A Step-by-Step Guide

Replacing the M&P 15-22 upper is a relatively simple process, but it's crucial to follow safety procedures. Always ensure the firearm is unloaded and clear of ammunition before handling.

Tools and Materials:

  • New M&P 15-22 compatible upper receiver
  • Punches (small and large)
  • Hammer (preferably a brass mallet)
  • Torque wrench (optional, but recommended)
  • Gun cleaning supplies (to clean the weapon before reassembly)

Steps:

  1. Unloading and Verification: Ensure the firearm is completely unloaded and the chamber is clear. Visually inspect the weapon and double-check for any ammunition.
  2. Remove Existing Upper: Use the small punch to push out the pivot pin and then the takedown pins. Gently separate the upper and lower receivers.
  3. Install New Upper: Align the new upper receiver with the lower receiver. Insert the pivot pin and tap it into place using the larger punch and hammer. Do not use excessive force.
  4. Secure Takedown Pins: Reinsert and tap in the takedown pins with the smaller punch and hammer.
  5. Verification and Function Test: After installation, carefully check that all parts are correctly seated and function properly. Perform a function test in a safe environment, ensuring the rifle operates smoothly before taking it to the range.

Maintenance After Replacement

Regular cleaning and maintenance of your new upper receiver are crucial for ensuring its longevity and performance. Always refer to the manufacturer's instructions for specific cleaning recommendations.
