TTI - 6.03mm 300mm Inner Barrel GBB Cut Chronograph knocker lock and valve knockerTTI 6. 03mm 300mm Inner Barrel The TTI 6. 03mm 300mm Inner Barrel is a precision tight bore upgrade barrel, GBB cut for gas blowback pistols and carbine kits. Machined to a true 6. 03mm internal diameter, it tightens the air seal around the BB to deliver improved accuracy, range and shot to shot consistency over a standard bore barrel. The 300mm length suits longer GBB platforms and carbine conversion kits, making it an easy drop in performance
