If you own a Tokyo Marui G17 or G18 GBB pistol, precision is likely at the top of your wish list. The Maple Leaf 6.02mm Inner Barrel and 60 Degree Hop-Up Set delivers exactly that in one complete, drop-in package.

The centerpiece is a high-quality 6.02mm precision bore barrel, crafted from durable brass and aluminum. This tighter diameter creates a superior air seal around the BB, boosting muzzle velocity and significantly improving shot-to-shot consistency. The result is tighter groupings and a flatter trajectory, giving you the edge in both range and accuracy.

Complementing the barrel is a 60-degree hop-up rubber, formulated to provide optimal backspin for standard-weight BBs. It ensures consistent lift and extends your effective engagement distance without the unpredictable flyers that plague stock setups.

The set also includes a rigid metal hop-up chamber, replacing the factory plastic unit that can flex under pressure. This metal chamber locks the barrel and hop-up rubber into perfect alignment, ensuring stable airflow and dependable performance with every shot.

At 97mm in length, this set is a direct fit for the Tokyo Marui G17 and G18 platforms. It transforms a reliable sidearm into a precision instrument, offering improved power, accuracy, and range with minimal effort. For anyone serious about upgrading their G-Series pistol, this is the definitive solution
