Description

The LAYLAX Prometheus EG Barrel is a 185mm internal barrel made for compact AEGs such as the Tokyo Marui M4 PMC and similar short-barrelled AR-15 platforms. Its 6.03mm tightbore diameter is designed to limit air escaping past the BB, helping to make better use of the available air volume and support consistent shot-to-shot performance from a short outer barrel.

Machined on CNC equipment from high-tensile stainless steel, the barrel is built to resist flex and cope with the vibration of high-cycle gearboxes. The internal bore is mirror-polished and the muzzle crown is squared, so the BB leaves through a uniform surface. For CQB-focused builds where manoeuvrability matters, this gives a straightforward accuracy upgrade without changing the outer barrel length.

  • 185mm length for compact M4 PMC-type AEGs
  • 6.03mm tightbore internal diameter
  • CNC-machined high-tensile stainless steel
  • Mirror-polished bore and squared muzzle crown
