Madbull Python Tight Bore Barrel

This barrel is designed specifically for 1911-style platforms, but compatibility can vary between manufacturers like Tokyo Marui, KJW, or WE. We recommend verifying your current barrel length against the 112mm specification before purchasing to ensure a proper fit.

The 6.03mm diameter creates a tighter seal around the BB as it travels down the barrel. This minimizes air leakage and stabilizes the BB's flight path, which typically results in better grouping and improved shot-to-shot consistency compared to standard stock barrels.

Yes. Because the tolerance is tighter, you must use high-quality, polished ammunition. Low-quality or inconsistent BBs are more likely to jam in a tight-bore barrel, which can damage the internal surface or cause performance issues.

The hard-coating creates an exceptionally smooth internal surface that reduces friction as the BB travels through the barrel. This lower friction helps maintain velocity and ensures the BB exits with a more predictable spin, contributing to the barrel's overall accuracy.

Installation requires field-stripping your 1911 pistol and removing the hop-up unit. If you are comfortable with basic airsoft maintenance and disassembly, it is a straightforward process, but take care not to damage the hop-up bucking during the transfer.
