An aftermarket airsoft AEG inner barrel is to guide the BB and ensure it exits the gun with optimal range and accuracy. Benefits of upgrading the inner barrel include increased accuracy and consistency, improved range, and higher velocity, achieved through factors like a tighter diameter, smoother finish, and appropriate length. A well-maintained inner barrel is crucial for performance and preventing malfunctions.
Purpose
• Guides the BB: The inner barrel is the pathway the BB travels through after being propelled by pressurized air.
• Affects range and accuracy: The length of the barrel directly impacts how far the BB can travel and how accurately it flies.
• Interacts with the hop-up: It's the component where the hop-up's backspin effect is fully realized as the BB is accelerated before exiting the muzzle.
Benefits of upgrading
• Increased accuracy and consistency: A smoother, more polished inner surface reduces friction and inconsistencies, leading to a more stable and predictable BB trajectory.
• Improved range and velocity (FPS):
◦ Tight-bore barrels: A smaller inner diameter (e.g., 6.01mm to 6.03mm) can increase velocity by creating a better air seal around the BB, leading to more compression.
◦ Longer barrels: A longer barrel can improve accuracy, particularly at long distances, because the BB receives guidance for a longer period, leading to a more stable flight path.
• Higher FPS: A tight-bore barrel can increase the muzzle velocity of the BB, while a longer barrel provides more time for acceleration.
• Reduced friction: Smoother barrels lose less kinetic energy as the BB travels through them, helping maintain velocity and power.
Factors to consider when upgrading
• Length: Choose a length appropriate for your replica type (e.g., long for rifles, shorter for SMGs or CQB) and playing style.
• Diameter: Tight-bore barrels offer greater accuracy but can be less reliable with dirt or low-quality BBs, so consider your typical playing environment.
• Material: Many aftermarket barrels are made of stainless steel for durability and a smoother finish.
• Maintenance: Regularly cleaning the barrel to remove dirt, debris, and grime is crucial to maintaining performance and preventing jams.
