Lambda 01 Airsoft 6.01mm TM GBB / MWS Barrel 250mm Long Stainless Steel

Lambda 01 Airsoft 6.01mm TM GBB / MWS Barrel 250mm Long Stainless Steel

The Lambda 01 6.01mm GBB / MWS Inner Barrel 250mm is a premium precision Airsoft barrel designed specifically for the Tokyo Marui M-4-A1 MWS Gas Blowback Rifle platform.

Manufactured in Japan from high-grade SUS304 stainless steel, the Lambda01 series is designed for performance-focused Airsoft builds where barrel quality, rigidity and manufacturing precision are a priority.

Precision 6.01mm Tight Bore

The Lambda01 features an extremely precise 6.01mm internal diameter, which Lambda describes as manufactured to micron-class precision.

The tight internal bore provides close control around the BB as it travels through the barrel. When combined with a correctly configured hop-up system and high-quality precision BBs, it provides an excellent foundation for achieving consistent shot-to-shot performance.

SUS304 Stainless Steel Construction

Lambda manufactures this barrel from SUS304 ultra-precision stainless steel, providing excellent rigidity, durability and resistance to corrosion.

The rigid stainless construction helps maintain the precisely manufactured internal dimensions while providing a durable upgrade over many standard factory inner barrels.

Precision CNC Machined & Hand Finished

Each barrel is produced using high-precision CNC lathe machining before undergoing a hand-finishing process by skilled technicians.

This combination of precision machining and individual finishing is a defining feature of Lambda's premium inner barrel range.

Designed for Tokyo Marui MWS

At 250mm long, Lambda officially specifies this version for the Tokyo Marui M4A1 MWS Gas Blowback platform.

Its GBB/MWS configuration makes it an excellent choice when replacing the original inner barrel or building a performance-focused MWS hop and barrel setup.

Made in Japan

The Lambda 01 6.01mm MWS 250mm Stainless Steel Inner Barrel is an excellent upgrade for Airsoft players looking to build a precisely tuned Tokyo Marui MWS.

For the best results, pair the barrel with a quality compatible hop rubber and correctly configured hop-up chamber. Due to its extremely tight 6.01mm bore, we recommend using high-quality precision Airsoft BBs and regularly cleaning the barrel to maintain consistent performance.
