The MadBull Steel Bull is the most affordable steel tightbore barrel for airsoft AEGs. MadBull's Black Python precision inner barrel is known to be one of the best airsoft inner barrels. The new Steel Bull tightbore delivers the same quality in a new steel barrel for unbeatable accuracy.
The MadBull Steel Bull is constructed out of a quality stainless steel extrusion, and precision polished to exactly 6.03mm diameter. The 6.03mm inner diameter provides the ideal mix of increased FPS and accuracy with consistent hop-up spin. Steel is stiffer than aluminum and reduces vibration from the gearbox for a more stable barrel. The stainless steel finish is extremely slick for best performance.
The 509mm Steel Bull tightbore is designed for M16, SR-25, M14, or other 20 inch barrel AEGs, or for use in any M4 with a long suppressor.
