Understanding the 15-22 Upper: A Deep Dive
The 15-22 upper receiver is more than just a collection of parts; it’s the heart of the Smith & Wesson M&P 15-22 rifle. Unlike a standard AR-15 upper, the 15-22 upper is specifically designed for .22LR ammunition. This necessitates a different bolt carrier group, barrel, and overall design to ensure reliable cycling and accuracy. The 15-22 was introduced to offer a cost-effective and enjoyable way to train with an AR-15 platform, allowing shooters to practice fundamentals without the expense of centerfire ammunition.
Core Concepts: The 15-22 upper houses the bolt, barrel, and charging handle. It’s typically made from a high-strength polymer to reduce weight and cost.
