Laylax Prometheus EG Inner Barrel – TM M4A1 MWS (6.03mm / 370mm)
The Laylax Prometheus EG Inner Barrel is a precision aftermarket inner barrel designed specifically for the Tokyo Marui M4A1 MWS gas blowback rifle. At 370mm in 6.03mm bore, it replaces the factory MWS inner barrel to deliver improved shot consistency — the 6.03mm bore provides tighter BB guidance than standard TM factory specifications while remaining compatible with the wide range of BB quality levels that GBB platforms typically see in normal use.
Prometheus is Laylax’s performance barrel brand, with a well-established reputation in the precision airsoft upgrade market. The EG (Elment Grade) specification provides the correct dimensional tolerance for the MWS platform. For TM M4A1 MWS owners looking to improve range and consistency from the factory platform, this is the correct precision barrel upgrade for the MWS bore and length specification.
