“- Melonite coated barrel: Melonite coating reduces internal barrel friction which extends the barrel life. Melonite coating also improves accuracy due to tighter coating tolerances and improves muzzle velocity by over 100 FPS. With no chrome lining to flake or peel over time, these melonited barrels will outlast hard chrome lined barrels two to one!”
