Description
The LAYLAX Nine Ball 6.00mm Power Inner Barrel is a 370mm internal upgrade for the Tokyo Marui M4A1 MWS gas blowback rifle series. Its 6.00mm bore is tighter than the 6.03mm and 6.05mm bores commonly used in aftermarket barrels, reducing clearance around the BB and limiting gas bypass. This focuses the expanding gas behind the projectile, supporting muzzle velocity and gas efficiency for long-range outdoor builds.
Manufactured by CNC machining from high-strength stainless steel, the barrel is intended to resist thermal expansion and flexing during rapid fire. The internal surface is mirror polished, and the muzzle crown is squared. It is aimed at MWS owners and upgrade workshops looking to tune a Tokyo Marui M4A1 MWS GBBR with a tight-bore barrel.
