AA Precision Inner Barrel VSR-10 / GBB, 6.01 mm - 430 mm

Precision Inner Barrel by Action Army

This tight bore barrel from Action Army delivers improved accuracy, consistency, and range by minimizing the air space around the BB during flight. This results in better BB stability and eliminates wobbling, enhancing precision. More compressed air stays behind the BB, increasing its muzzle velocity. Made of electro-chromed brass with a highly polished interior for optimal smoothness and performance.

Important Notes

• Ammo cleanliness and quality are critical to shooting performance. Especially with tight bore barrels, prevent debris from reaching the BBs (e.g., via the magazine during prone use). Clean the barrel regularly to maintain accuracy.
  
  
• Select barrel length based on the original inner barrel length in your gun.
  
  
• Choosing the perfect barrel length for your setup requires consideration of several physics factors.
  
  
• The key is the air volume ratio in the cylinder (or gas output), known as the Cylinder:Barrel Ratio. Longer barrels and heavier BBs require more air, which is why different cylinder port types exist. For gas setups, take into account the gas power or HPA regulator output.
