The Smith & Wesson M&P 15-22 is a popular .22 LR pistol caliber carbine, perfect for plinking, training, and introducing new shooters to the world of firearms. However, like any firearm, parts wear out or you might simply want to customize your rifle. Replacing the upper receiver is a common upgrade or repair. This guide provides a detailed overview of the process, helping you understand what's involved and what to consider.
Why Replace Your M&P 15-22 Upper Receiver?
Several reasons might necessitate replacing your M&P 15-22 upper receiver:
-
Wear and Tear: Extensive use can lead to wear and tear on the upper receiver, affecting its functionality and accuracy. This is especially true if the rifle is used frequently in harsh conditions or exposed to dirt and debris.
-
Upgrades: Upgrading to an enhanced upper receiver can improve performance. Many aftermarket manufacturers offer uppers with enhanced features like improved sights, different barrel lengths, or free-floating handguards.
-
Damage: Accidental damage to the upper receiver, such as drops or impacts, may render it unusable. Replacing the damaged part is crucial for safe and reliable operation.
-
Customization: Personalization is a big part of firearm ownership. Switching to a different upper receiver allows you to change the aesthetic look and feel of your M&P 15-22.
Choosing a Replacement Upper Receiver
Selecting the right replacement upper receiver is critical. Consider these factors:
-
Compatibility: Ensure the upper receiver is specifically designed for the Smith & Wesson M&P 15-22. Not all AR-15 uppers are compatible.
-
Material: Aluminum is the most common material, offering a balance of strength and weight. However, some manufacturers offer uppers made from other materials like steel, which provides enhanced durability but adds weight.
-
Features: Consider features like the type of handguard (M-LOK, KeyMod, Picatinny), the barrel length, and the included sights. Choose features that align with your needs and shooting style.
-
Manufacturer Reputation: Research manufacturers known for producing high-quality, reliable AR-15 components. Reading reviews from other users can help you make an informed decision.
Steps to Replace Your M&P 15-22 Upper Receiver
Disclaimer: Replacing firearm components requires familiarity with firearms and proper safety procedures. If you are uncomfortable performing this task, seek assistance from a qualified gunsmith. Always ensure the firearm is unloaded and the safety is engaged before commencing any work.
