Upgrade your inventory with premium Japanese-engineered performance. The Laylax 6.00mm Steel Inner Barrel is the definitive internal upgrade for the wildly popular MK23 Gas Pistol platform. Designed for players demanding maximum range and pinpoint accuracy from their stealth sidearms, this ultra-tight bore barrel delivers exceptional air compression, leading to increased FPS and tighter shot groupings.

Constructed from high-grade rigid steel, this barrel eliminates vibration and flex during firing, vastly outperforming standard factory brass barrels. This is a high-margin, fast-moving upgrade component essential for any airsoft retailer catering to snipers, recon players, and dedicated MK23 enthusiasts.
