Laylax Stainless Steel Inner Barrel for AEG Type W (6.03mm - 280mm)

Unlock pinpoint long-range precision, improved grouping tightness, and optimized gas/air compression with the Laylax Stainless Steel Inner Barrel for AEG Type W (6.03mm - 280mm)! Manufactured in Japan under the industry-standard Prometheus label by Laylax, this precision inner barrel represents the pinnacle of aftermarket airsoft upgrade engineering.

6.03mm Tightbore Precision & Superior Polishing Featuring a strict 6.03mm inner diameter tolerance, this tightbore inner barrel creates a tighter air seal behind the 6mm BB as it travels down the bore. This efficient seal minimizes air leakage around the projectile, yielding a noticeable boost in overall FPS (feet per second) and consistency between shots without requiring a mainspring change. The interior wall undergoes an intensive mirror-polishing process to eliminate micro-abrasions, significantly reducing friction for a flatter, more stable flight trajectory.

Durable Stainless Steel Construction & Type W Design Unlike softer brass factory barrels that can flex, nick, or oxidize over time, the Laylax Prometheus barrel is CNC-machined from high-grade stainless steel. This heavy-duty material offers high structural rigidity, resisting vibration during high-rate-of-fire full-auto bursts while remaining completely immune to corrosion and humidity. The "Type W" design features precision-milled hop-up window geometry and locking side notches compatible with standard AEG hop-up chambers and aftermarket buckings, ensuring a snug, air-tight drop-in fitment.

Ideal Length for Compact Carbine & SBR Platforms At 280mm in length, this barrel is specifically sized for compact carbines and SBR setups—including short M4/AR-15 builds, MK18-style handguards, SIG MCX platforms, and similar airsoft models. It allows operators to upgrade their factory setup cleanly inside standard outer barrels or conceal extended length setups using mock suppressors and tracer units.

Whether you are building an elite CQB primary, fine-tuning an SBR project, or simply looking to eliminate stray shots downrange, the Laylax Stainless Steel Inner Barrel for AEG Type W (6.03mm - 280mm) delivers the unmatched Japanese craftsmanship needed to out-range the competition.
