T-N.T. Studio APS-X Hop-Up System with 97mm Inner Barrel for Tokyo Marui Glock 17/18C

Any Tokyo Marui GBB is already an accurate pistol so designing a new inner barrel and hop up is a challenge. The APS-X T-N.T APS-X Hop-Up System actually helps push BBs past 30 metres, which is something that Marui guns always had issues with due to their low power. It'll stay accurate as the 6.03mm inner barrel and Hop Up rubber is included in the set up!
