Madbull Python Ver.2 Barrel

No, this specific barrel is designed exclusively for the PSG-1 and G3 series platforms. It will not fit standard M4 or other AEG models due to differences in hop-up unit alignment and barrel length requirements.

A 6.03mm diameter is considered a 'tightbore' barrel, which reduces the amount of air that escapes around the BB as it travels down the tube. This creates a more consistent air seal, typically resulting in a slight increase in muzzle velocity and improved grouping at long ranges.

Yes, the hard-coating creates a smoother surface finish than standard brass or aluminum barrels. This reduction in friction helps prevent BB jams and ensures that the projectile travels through the barrel with less resistance, which is critical for maintaining accuracy.

Because this is a precision 6.03mm barrel, you should only use high-quality, polished 6mm BBs. Using low-quality or inconsistent BBs in a tightbore barrel significantly increases the risk of jamming or damaging the internal surface.

You should clean the barrel periodically using a soft cleaning rod and a small amount of silicone-free lubricant or isopropyl alcohol. Keeping the internal surface free of debris and residue is essential to maintaining the performance benefits of the hard-coating.
