Are all gas blocks created equal? Gas blocks, crucial components in firearm systems, are available in two primary variants: standard and adjustable. Standard gas blocks permit a fixed quantity of gas to pass through the system, but some may inadvertently allow excessive gas, a condition referred to as “overgassing.” This phenomenon, observed in some standard gas blocks, occurs when more gas enters the system than is required for optimal functioning, potentially leading to performance issues and increased wear on the firearm. To ensure a firearm operates efficiently and reliably, choosing the appropriate gas block type and tuning it correctly is essential. [Published on September 12, 2018]

The Aero Precision gas block set includes 10-32 x 3/16 set screws, which are made from steel and feature a knurled cup point. These set screws are manufactured in the USA. These specific screws play a crucial role in securing and stabilizing the gas block within the firearm assembly, ensuring its proper functioning. The 10-32 thread size and 3/16-inch length are designed to provide a secure and reliable fit for the gas block.
