BB Curves Up or Down when Firing

< All Topics

If this is happening on a gun or pistol with a Hop-Up then a small adjustment will fix the problem. Please see your gun’s manual for information on how to just your Hop-Up.

If it is not a Hop-Up issue, how about looking at one of these possible issues:

ABNORMALITY OF BB PELLET
Avoid using poor quality or deformed BB pellets. Use high-quality, seamless, and perfectly round BBs.

ABNORMALITY IN SECTIONAL PARTS OF THE BARREL
Replace with new parts if there are scratches or deformities in internal parts of BB chamber/inner barrel.

SYNCHRONIZATION FAILURE BETWEEN MOVING PARTS
Lubricate slide, frame assembly, gun barrel, and other movable parts with oil or clean with warm soapy water and re-lubricate.

YOU HAVE LUBRICANT ON THE HOP-UP MECHANISM
Clean your Hop-Up and inner barrel with the correct products.

HOLDING AND GRIPPING GUN INCORRECTLY
Try to avoid wrist or handshake, grip correctly when shooting. Grip gun with both hands where possible.
