The TTI 6.03mm 285mm Inner Barrel is a precision tight-bore upgrade barrel, GBB cut for gas blowback pistols. 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 285mm length is a versatile fit for mid-to-long GBB platforms, making it an easy drop-in performance upgrade. Each barrel is precision finished to reduce friction and air loss as the BB travels down the bore.
