  • 3300 x 0.20g BBs
  • Low cost and high quality
  • Perfect for CQB and GBB pistols

If you are shooting so much you are emptying your bank account as fast as you empty your magazine, more affordable BBs are the key to keeping up the habit. Often, with affordability comes compromise, but not with ASG's Q Blaster BBs! These 6mm Airsoft BBs are supplied in a resealable bottle containing 3300 BBs approximately and are polished and coated for smooth reliable feeding. These are the 0.20G variety, perfect for the average AEG, shotgun or GBB pistol and especially good for CQB where the extra projectile speed of a lighter BB can be a huge benefit when engaging moving targets.

Tolerance is slightly wider than Blaster Devils but still minuscule, promising +/- 0.03mm variance at the absolute maximum. These BBs would be great for CQB use and use in platforms which won't need the extra precision of Blaster Devils to show the enemy who is boss!
