AA Precision Inner Barrel AEG, 6.03 mm – 470 mm

Precision Inner Barrel by Action Army
This tight bore barrel from Action Army ensures better grouping, improved accuracy, and extended range by minimizing the space around the BB as it travels through the barrel. This stabilization helps prevent the BB from wobbling, which would otherwise decrease precision. More air stays behind the BB, giving it a higher muzzle velocity. The barrel is made of electro-chromed brass and features a highly polished interior for maximum smoothness.

Notice

BB quality and cleanliness, along with the barrel and hop-up rubber, are crucial for accurate shooting. For tight bore barrels, avoid dirt and debris – especially in mags during crawling – and regularly clean the barrel.
Select the appropriate barrel length according to the stock inner barrel length of your gun.
Choosing the ideal length involves balancing several physical factors – it’s almost an art form.
The key factor is the volume ratio between the cylinder and the barrel, also known as the Cylinder:Barrel Ratio. A longer barrel or heavier BBs require more air volume, which is why there are different types of cylinders with or without ports. In gas guns, it depends on gas power or the HPA regulator’s output.
