If you are after a bit more accuracy from your GBB pistol, a tight bore barrel is the easiest and most effective solution! Introducing the 6.02mm Tightbore Inner Barrel from Maple Leaf, legends in the inner barrel market for their innovative crazy jet system. This inner barrel is of a standard design with a 6.02mm bore which will improve accuracy over stock inner barrels and provide a slight increase in FPS.

Full description


The 6.02mm Tightbore Inner Barrel from Maple Leaf features their new Hybrid inner barrel cuts, meaning the barrel is compatible with TM based GBB pistols with the VSR style bucking (WE, Umarex G series etc.) but also AEGs when used with the Maple Leaf Hybrid bucking. Due to its length, we recommend this for GBB pistols but if you are making an ultra short AEG this can also be used when combined with the correct HOP bucking.

The inner barrel is constructed from stainless steel and has a high polished internal surface for minimal friction, and a deep and smooth crown to ensure your BB leaves the barrel smoothly and consistently. This barrel is cut for either VSR/GBB style HOP buckings or Maple Leaf Hybrid buckings when used in an AEG.
