We’ll examine its features, performance, and address common user questions, providing you with the information you need to make an informed decision.
Understanding the Advantages of a Side Charging Upper
Before focusing specifically on PSA's offering, let's understand why side charging uppers are gaining traction. The primary benefit lies in enhanced ergonomics and functionality, particularly in scenarios where a traditional charging handle might be cumbersome or inaccessible:
-
Improved Accessibility: The side charging handle allows for easier manipulation, especially when using accessories like optics, suppressors, or when operating in tight spaces or confined positions.
-
Ambidextrous Operation: Side chargers typically offer ambidextrous operation, benefiting both right and left-handed shooters.
-
Reduced Charging Handle Interference: Eliminates the need to reach over the optic or other accessories mounted on the receiver, streamlining the charging process.
