Product Information

TTI 6.03mm 116mm Inner Barrel

The TTI 6.03mm 116mm Inner Barrel is a precision 6.03mm tightbore inner barrel cut to 116mm, machined to a TM spec GBB cut so it drops straight into compatible gas blowback pistols. It is also compatible with the Action Army AAP-01.

The tighter 6.03mm bore reduces air loss around the BB as it travels down the barrel, delivering more consistent velocity and tighter groupings than a standard bore. The longer 116mm length and precision-finished surface help squeeze out extra accuracy and a cleaner BB release.

Key features:

Precision 6.03mm tightbore inner barrel

Cut to 116mm length

TM spec GBB cut for easy fitment

Improved air seal and more consistent velocity

Compatible with the Action Army AAP-01

Fitting & Returns

Replicas vary between makers and production batches, so a part can sometimes need work to fit. If you're not confident fitting it yourself, we recommend using an airsoft tech. Not sure a part suits your replica? Email info@ebog-designs.co.uk before you order.

Unfitted, unmarked parts in their original packaging can be returned for a full refund if you ask within 30 days of receiving them. Fitted or altered parts usually can too, less a deduction for any loss in value. Made-to-order items and gift cards have different return rules.

If a part is faulty, not as described or not what you ordered, there's no deduction, even if you've fitted it. Damage from incorrect fitting after delivery isn't a fault, unless it was caused by wrong or incomplete instructions, whether they came with the part or from us. Full details are in our Refund Policy.

Upgrade parts are sold for use within the legal power limits that apply where you are.

Finishes can vary slightly between batches, and colours can look different on screen.

None of this affects your statutory rights.
