Ballistic Advantage Melonite Gas Tube – Carbine Length AR-15

The Ballistic Advantage Melonite Gas Tube is a direct replacement for worn or damaged carbine-length gas tubes in AR-15 platform rifles. Gas tubes are critical components that channel propellant gases from the barrel's gas port back to the bolt carrier group, cycling the action. Over time, gas tubes can corrode, develop carbon buildup, or sustain damage during barrel removal. This tube restores reliable function with a durable Melonite finish that resists corrosion and heat better than standard stainless steel.

Manufactured from 304 stainless steel and treated with a salt-bath nitride (Melonite) coating, this gas tube offers superior surface hardness and resistance to erosion from high-temperature gases. Installation requires removal of the handguard and gas block, then alignment and pinning through the gas block—straightforward for anyone familiar with AR-15 maintenance, though a roll pin punch set is necessary. The tube includes a roll pin for securing to the gas block.
